Twitter is on the prowl. Though it made its last acquisition more than a year ago, company founder Biz Stone said on Tuesday that it's looking to add to the stable. There aren't any specific targets yet -- at least none revealed -- and Twitter is keeping its options open. The likely pool of potential acquisitions consists of third-party Twitter application developers, which is largely responsible for the micro-blogging service's growth in popularity.

Stone, one of Twitter's founders, said at a Tel Aviv news conference, "As our attention is grabbed by some of these developers, we will take a hard look at them." This refers to companies that develop applications for Apple's (AAPL) iPhone and Research in Motion's (RIMM) Blackberry. It also refers to developers for the Web and desktop, such as HootSuite and TweetDeck.

Twitter calls Google (GOOG) a "good role model," but says it isn't ready to rush down the road to advertising.

Nonetheless, an ad-based revenue model is something that cofounder Biz Stone says they "will be looking to do down the line." But, for now, he continues, Twitter is focused on "creating value for our users." For now, revenue generation ideas are being put on paper, "and we're definitely going to get to them," Stone says.

Yahoo! (YHOO) is the latest company that wants to optimize its search results for Twitter. This follows moves by Microsoft (MSFT) and Google (GOOG) to integrate Twitter data into their search results. Unlike its competitors, however, Yahoo! wants to do this without spending a dime (well, without giving a dime to the hot new social media platform).

Twitter's microblogging service has become famous not only for its rapid growth but also because it's found no way to turn it into revenue. Its recent discussions with Microsoft and Google demonstrated that Twitter can indeed bring in some cash -- by licensing its data for use in fine-tuning search engines. With two of the top search engines now optimizing for Twitter, it was only a matter of time before Yahoo! would rush to join the party.

Once upon a time, Mac users could brag they were much safer from malicious electronic attacks. After all, in the days before Google (GOOG), when Microsoft (MSFT) was the only uber-player in town, Windows was the perpetual malware target. Phishers, however, aren't discriminating; they're just looking for an account to plunge. So, both Apple (AAPL) and Microsoft users are threatened. Virus writers do tend to focus on the Windows operating system, which owns 90% of the OS market, but phishers are platform independent.

Phishing involves attempts to get a user to reveal information about their accounts. Once the soon-to-be victim clicks that link or fills out a form, the "transaction" is complete -- no operating system interaction necessary. As a result, there really isn't any advantage to using a Mac over a PC.

Imagine taking the personal connections and interactions that occur every day on the likes of Facebook and Twitter... and bringing them to bear on an education. To a large extent, this hasn't been done yet, but the potential is profound. In a new report by the Center for Community Survey for Student Engagement, two-year programs aren't taking advantage of the tools at their disposal -- plenty of growth is still possible. Kay McClenney, director of the CCSSE, says, "Colleges are not taking advantage of that particular set of tools for making connections with students to the extent that they could."

The recession has led everyone with a budget to question ever line. From households to businesses to state and federal governments, nothing is sacred. Finding new ways to get the same result without spending the same amount mean not having to make sacrifices. NASA has been under considerable financial pressure, as many question the value of sinking cash into space travel. So, it has to get creative in justifying its existence ... and in generating excitement about the agency and what it does.

When the space shuttle launches on Monday, 200 thumbs will be at the ready. NASA has deputized 100 of its top fans on Twitter to come to the launch and tweet the experience. These fans are estimated to have more than 150,000 followers, all with the potential to retweet the messages they see. Every click of an iPhone or Blackberry will give NASA more exposure, building the excitement it needs to keep the operation afloat. So, whether you realize it or not, the launch is being brought to you by Twitter, Apple (AAPL) and Research in Motion (RIMM), even if only implicitly.

BT Group, which virtually owns the UK telecommunications market, isn't waiting for Google (GOOG) to launch a full attack. The company probably expects to be under assault from the search engine (and advertising and e-mail) giant, so it's taking early action. Google Voice is still being tested, but words like "free" and "powerful" and "internet-based" are bound to inspire fear in even the most established of companies.

To protect itself from the eventual attack from Mountain View, BT picked up Ribbit Mobile, and testing is in progress. Ribbit's technology has some overlap with Google Voice and even beats it with a few capabilities, according to Bloomberg. Ribbit just launched its beta product this month. It allows either the user's current phone number or a new one from Ribbit -- which is no different from Google's alternative. The product suite is generally the same, with phone- and web-based voicemail retrieval and automatic transcriptions that can be sent by text message or e-mail. For an extra fee, BT's Ribbit does provide human transcription, though it is free during testing. And, calls can be taken directly from a computer, using a microphone and speakers.

Morale has plunged among military personnel in Afghanistan as a result of record violence in the war, according to the U.S. Army. A battlefield survey found that the situation is particularly problematic for soldiers on their third and fourth combat tours, and junior enlisted soldiers are most likely to experience marital problems because of deployment. Though it's not a complete solution, the study did find that limited doses of technology – either through video games or internet access – can help.

The study, obtained by NBC News, revealed that more than 20% of soldiers are experiencing combat stress, and half of them are having difficulties getting professional help. Combat Stress units in Afghanistan, the report says, are "undermanned," and this type of unit has no presence in the southern part of Afghanistan, where most of the combat is taking place.

Michael Moe knows how to make headlines: Talk about Twitter and predictably people will bite (I'm proof of that). He led the team at NeXt Up Research that calculated the value of the micro blogging service and arrived at $526 million to $674 million -- half what Twitter is generally believed to be worth.

Really?

The team estimates that Twitter will generate revenues of $114 million to $134 million in 2013. In 2014, Twitter is expected to post revenues of $126 million to $148 million. This is far more conservative than the valuation implied by the company's most recent round of venture capital investment, which puts the company's worth at more than $1 billion.

For News Corp. (NWS), MySpace is the mistake that keeps on costing. It's bad enough that Murdoch's empire paid $500 million for the social networking platform shortly before Facebook knocked it from the premier spot in the social media beauty pageant, but now we also know that News Corp. has committed $350 million to office space for MySpace that will never be used.

News Corp is shelling out more than $1 million a month for 420,000 square feet in Playa Vista, near Los Angeles International Airport. The deal was signed in August 2008 by Peter Levinsohn, former president of the Fox Interactive Media Unit. At the time, he issued a chest-puffing memo claiming it was "the single biggest real-estate transaction in Los Angeles in the last 25 years." Fortunately, he didn't mix the word "genius" in there at all.

The Twitter ecosystem may be changing constantly, but most of that comes on the back of individual developers and outside companies. They beat on Twitter APIs to create new products that may win them glory, recognition or cash. Over the past month, though, Twitter itself has gotten into the game, releasing or announcing a handful of new features.

A new function for "retweeting" (echoing another's tweet to your own followers), changes to how trending topics are managed, and the ability to create lists are new tools intended to engage users ... on the Twitter.com website. Considered within the context of Twitter's changed terms of service this year, the upgrades may be part of a broader ad-based revenue plan.

Company attitudes toward social media sites vary. Some swing the doors wide open, allowing employees to tend to their Facebook farms and update Twitter statuses throughout the day. Others lock 'em down, keeping non-business site access to a minimum.

A recent study found that, in the United States, 77% of employees with Facebook accounts check in with the community from the office. And, the amount of time they're spending in this part of the online world is growing. In the United Kingdom, another study found that 57% log in regularly from work, costing their employers 40 minutes a day.

Philip Wicks, a consultant at Morse PLC, a technology research firm in London, "It isn't just something you can do for half an hour during a lunch break but all through the day and because of that, it has a huge impact because people aren't necessarily concentrating on what they should be doing during the day." He estimates that this translates to lost productivity of $2.25 billion a year.

It seems like the obvious move would be to block the sites, but William Beers of PricewaterhouseCoopers disagrees. "Instead of trying to shut it down, I think we should try to embrace these technologies, put in a nice policy that governs it and explain to users the risks related to it, provide some training and then see what business benefits we can have from it," he said.

Once upon a time, retailers measured success by the number of people walking by in the mall, how many entered the store, the percentage they spent, and basket size. Now, a world of zeroes and ones has changed their perspective entirely. Social media is expected to be the star during the coming holiday season, with retailers pushing Facebook, YouTube, and Twitter content to get in front of consumers and affect either online or in-store purchases. Smaller Christmas budgets are expected, so the fight is on to garner as large a share as possible of a shrinking pie.

Of course, nobody would come out and say, "Social media is nonsense, and I'm not getting anything for my investment." So, when the likes of Starbucks (NASDAQ: SBUX), JCPenney (NYSE: JCP), and Target (NYSE: TGT) say that social media is connecting them with their customers and leading to more effective campaigns and product launches, do take it with a grain of salt. What can't be ignored, however, is that they're committing more resources to social media marketing, even though it's still far too soon to tell if it will be effective.

Who needs venture capital money when you have litigation? Facebook was awarded $711 million in damages Thursday in an anti-spam case against Sanford Wallace, an internet marketer. The popular social networking platform went after Wallace for tapping its users' accounts without their permission and sending fake posts and messages.

Wallace has quite a reputation for spamming, having gained the nicknames "Spam King" and "Spamford" back in the 1990s, when he was good for up to 30 million spam e-mails a day.

Your e-mail account is a goldmine. Technology companies push hard to keep your data secure, but there are plenty of scumbags out there who always seem to find a new way to gain an edge over the guys in white hats. Phishers, in particular, are eager to find new ways to profit from your identity and information, and they're getting some new tricks.

Phishing scam activity was quiet at the beginning of this year, according to a report in USA Today, but these attacks surged 200% from May through September, says the X-Force team at IBM (NYSE: IBM). Webmail, social media and gaming accounts are their primary targets. E-mail access, in particular, is highly sought after, since they can be use to push out spam ... while bypassing filters.

These "virgin" e-mail accounts command top dollar: a digital criminal can pick up as much as $2 for a clean account from Microsoft (NASDAQ: MSFT) Windows Live, Google (NASDAQ: GOOG) Gmail, Yahoo (NASDAQ: YHOO) YahooMail or AOL (NYSE: TWX). This is more than twice the amount typically paid for a stolen credit card account, according to Fred Rica, principal in the security practice at PricewaterhouseCoopers. Many webmail users actually do half the criminals' job for them, with 33% using just one password online and 48% using only a handful.
