The Twitter-verse continues to get interesting. I've always felt that the returns are to be found around Twitter rather than with Twitter itself, and the venture capital community seems to be acting from the same position. Twitter interaction platform HootSuite just announced a new round of venture capital funding, with $1.9 million in fresh money coming in the door to support its growth efforts.

HootSuite, which was started by Invoke Media in November 2008, has evolved into a brand monitoring, file-sharing and social media integration utility. Only a year later, it has attracted more than 300,000 users, from Time (TWX) to Martha Stewart to the White House to Aol (AOL).BloggingStocks is among the Aol blogs using HootSuite.

The New York Times (NYT) is putting its 2.3 million followers to work. It isn't ready to start charging a la carte for Twitter advertising, but it is including the channel in the comprehensive packages it presents to advertisers. And, the Times isn't alone. Several media outlets (including BloggingStocks) have ads running through their Twitter streams, but this is still virgin territory, for the most part, and media companies are still feeling their ways through it.

Jack Dorsey is accustomed to dealing in small. In 2006, he co-founded social media sensation Twitter, which traffics in content bites that are no more than 140 characters in length. He left his position as CEO a year ago (and remains chairman) and is now focusing on his newest endeavor: mobile payments. He came up with the idea for his new company, Square, a year ago and hopes it will revolutionize how money is exchanged.

The first product that Square is bringing to market lives up to its name: it's a small cube-shaped credit card terminal that can plug into an iPhone's headset jack. The problem that the device is intended to solve is the swift and easy transaction of credit card payments for anyone. It was inspired by the plight of Dorsey's friend, Jim McKelvey, a glass artist who lost a $2,000 sale because he couldn't accept credit card payments.

It was only a matter of time. This week, social media platforms Twitter and LinkedIn announced new features that will undoubtedly appeal to corporate marketing departments, so Facebook hopped on the bandwagon. Its new preferred developer program is a step toward structuring the Facebook application development and services space, by endorsing providers known to the company.

The program is still in its infancy, which means there isn't much structure around it. According to AllFacebook, "[T]here's really no way to apply to be in the directory aside from being connected with the people over at Facebook." Fourteen vendors are already listed in the directory.

Twitter-watchers have been expecting the company to make some move toward corporate microblogging capabilities for months now. This is one of the two directions that the social media platform has on its agenda for generating revenue, and it is likely the one with the greater potential. The other, serving ads on Twitter.com, is currently constrained by the fact that nearly 70% of Twitter use occurs away from the company's website.

While all talk of corporate accounts is still shrouded in speculation, the obvious plan would be for corporate users to have more robust analytics and other marketing tools for which a premium would be paid. Among the tools being rolled out ostensibly in advance of this business model is a multi-user account model, in which several "Contributors," as Twitter is calling them, can tweet under the same umbrella.

It really didn't take Yahoo! (YHOO) long to pull the trigger. Only a few weeks ago, the perpetual also-ran in the search engine market announced that, like Microsoft (MSFT) and Google (GOOG), it would integrate Twitter data into its search capabilities, part of a race among the three companies toward "real-time search." Unlike its competitors, though, Yahoo! didn't shell out a dime for its access to the microblogging service's data, instead using existing developer tools to get what it needs.

Earlier this week, Microsoft announced that it wasn't in a rush to win in real-time search ... while indicating that it wasn't exactly lagging Google. Both companies have yet to demonstrate a fully integrated Twitter capability. While Yahoo! still has a long way to go, its announcement on Thursday suggests that it has an early lead, despite not having licensed any data from Twitter.

Facebook is implementing a new stock structure to make sure the founders retain control, immediately causing rumors about an impending initial public offering. Why would Facebook need Class A and Class B shares otherwise? Under the new structure, which is similar to Google's (GOOG), Mark Zuckerberg and other early entrants wouldn't have to worry about yielding the floor to outsiders when if the company goes public.

The stock structure was adopted to ensure that existing shareholders keep control on voting issues, according to Facebook statement. No details were given as to who the winners are in this arrangement, but a Wall Street Journal report says that, according to its sources, all current shareholders would be converted to Class B shares, which carry 10 times the voting rights of Class A shares.

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.

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.

An unemployment rate of 10.2% means that serious jobseekers are using every tool they can find. So, it's not at all shocking that social networking tools top the list, with LinkedIn, Facebook and Twitter leading the charge. Openings are being tweeted, hints of a new position are being monitored and hot candidates are being hit up directly, even if they aren't saying they're on the prowl for a new gig. Social media is a tool to use in a job hunt but not necessarily the only one, according to Challenger, Gray & Christmas. Instead, it makes sense to balance a search with many tools.

John Challenger, CEO, says, "The job search has changed radically over the last two decades with the advent of electronic mail, the internet, social networking, smart phones, etc. However, it is important to remember that all of these technologies simply enhance the job search; they will never replace the face-to-face connections that are critical to a successful search." But, he continues that "we feel that these new networking tools are essential and now advise all of the job seekers going through our program to open LinkedIn accounts and to consider other services such as Facebook and Twitter.

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.

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.

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.
