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.

GameStop (GME) posted what I thought was a mediocre third quarter. Total sales went up about 8%, and earnings per share increased a few pennies to 31 cents. When you think video games, you think growth. That doesn't feel like growth, does it? Not the kind that sends a stock to the moon, certainly. Furthermore, same-store sales saw a decrease of 7.8%, driven by lackluster hardware transactions. Indeed, we may be hitting a point in the console cycle where the demand for systems from Sony (SNE), Microsoft (MSFT), and Nintendo (NTDOY) has essentially been satiated.

Here's the big question on the mind of traders: unimpressive Q3 or not, should GameStop be bought now?

In tech circles, you will hear lots about "cloud computing." Essentially, this means that software applications are operated through Internet connections -- and processed in huge data centers. Often, the results include lower costs and easier maintenance.

Of course, the dominant player in cloud computing is Salesforce.com (CRM). And based on its latest quarterly report, the company continues to grow and innovate.

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.

Amazon, Inc. (AMZN) is in the clouds. So are Google, Inc. (GOOG), EMC (EMC) and Cisco (CSCO). Now, Microsoft Corporation (MSFT) is joining them, having announced on Tuesday its new Windows Azure cloud computing system. The new product will be released on January 1, 2010 -- a new solution for a new year.

Azure will deliver an online platform for the software development set to build their own mousetraps and provide plenty of storage space for users. Testing began a year ago, and full live version will be celebrated next year. For the first month, Azure will be free. The charges start in February.

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.

Analyst upgrades:

• Wells Fargo upgraded Qualcomm (QCOM) to outperform from market perform. The firm believes key risks have been eliminated, such as the license dispute with Nokia (NOK) and litigation with Broadcom (BRCM), and thinks Qualcomm is well-positioned for handset unit shipments growth. Wells has a $50 to $60 target range on shares.
• Oppenheimer upgraded Juniper Networks (JNPR) to outperform from perform as it views shares as compelling at current levels and thinks the company is well positioned for 2010. Opco set a $31 price target on the stock.
• FBR Capital upgraded Frontline (FRO) to outperform from market perform after raising its rating on the tanker industry to overweight. The firm raised its target on shares to $33 from $23.
• PetSmart (PETM) was upgraded to buy from neutral at Goldman.
• Career Education (CECO) was upgraded to equal weight from underweight at Barclays.
• Rosetta Resources (ROSE) was upgraded to buy from neutral at SunTrust.

It's easy to save the world when you've already taken care of yourself. But, we rely on these mavericks -- the wealthy who realize they can make a difference -- to do what we cannot on our own. So, it comes as a relief that Bill Gates, founder of Microsoft (MSFT) believes executive compensation is still too high.

It's a murky topic, and some forms of regulation, Gates believes, won't help. In a discussion on philanthropy at the 92nd Street Y in Manhattan, where many of the people Gates criticized send their kids for early education, the former CEO and still rich guy cites the $1 million executive salary cap required by law in 1993 as a big mistake. While compensation has to be controlled, he believes this measure backfired and thinks that other, similar efforts are doomed to fail now.

Even the thought is hard to believe for anyone who's been watching Apple Inc. (AAPL) over the long run. Once upon a time, the company was presumed dead, while Microsoft Corporation (MSFT) continued its march to market dominance. Today, Apple's $180 billion market value is evidence of a new era. Though it's still behind Microsoft's $250 billion, the company's rapid ascent and substantial market presence make at least speculation of catching up to the Redmond giant worth a few minutes of thought.

Microsoft is currently the most valuable technology company in the world, according to a Reuters report. Even Google, Inc (GOOG), with its astounding brand recognition and position as gateway to the internet, is worth "only" $136 billion. Apple, which was once considered a computer company that sold into education and appealed to some graphics geeks, has reasserted itself as a major global presence.

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.

The latest litigation has Intel Inside.

The State of New York is going after Intel (NASDAQ: INTC) over antitrust allegations. State Attorney General Andrew Cuomo is accusing the largest chip manufacturer in the world that it is trying to secure a global monopoly for microprocessors.

For several years, Cuomo said that Intel has pushed the likes of Dell (NYSE: DELL) and Hewlett-Packard (NYSE: HPQ) to agree to the exclusive use of Intel's gear in exchange for billions of dollars in payments. The hefty cash outlays have given what Cuomo called a "stranglehold" on the market.

Google Inc.'s (NASDAQ: GOOG) Google Apps project has gained steam (and customers) since its introduction a few years ago. Although it's not yet a true competitor to Microsoft Corporation's (NASDAQ: MSFT) Office juggernaut, it is making headway.

The "software as a service" camp is doing nothing but speeding up, as small and large businesses would like to offload expensive software installations and just use the Internet as a vehicle for getting things done across boundaries and time zones. Microsoft, though, is not capitulating just yet.

Today was a whip-around day. All day. Despite better construction and better manufacturing employment data, the markets looked like they were trying to roll over again before the end of day rally took stocks back up on the day. It seems that bargain hunters won over the fear that was felt earlier this afternoon.

Here were today's unofficial closing bell levels:

Dow 9,789.21 +76.48 (0.79%)
S&P 500 1,042.82 +6.63 (0.64%)
Nasdaq 2,049.20 +4.09 (0.20%)
