Look for a LinkedIn IPO, but not in the near future. Company co-founder and executive chairman Reid Hoffman has revealed his (and his investors') exit strategy, even if it could take a while to get there. Any social media company IPO would take a while to get off the ground in this market, since companies are being incredibly cautious. So, "not anytime soon" could coincide with a change in market conditions ... but Hoffman stopped well short of that.

At an event in London to celebrate LinkedIn's hitting the 3 million user mark in Britain, Hoffman said about the company's IPO prospects, "Probably at some point a balance will occur when that's the right thing. That will not occur in the near term." Worldwide, LinkedIn has 53 million members.

Google (GOOG) just picked up another promising startup in its effort to gain some ground in the online visual advertising market. Teracent, which was formed three years ago, is becoming part of the search engine giant.

Yahoo! (YHOO) currently leads the market in display advertising sales, and Google has been trying push into the space. Last year, this led to its acquisition of online ad service DoubleClick, but that was a first step rather than a total solution to Google's display ad ambitions.

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.

Often, we confuse winning with being the best. This isn't always the case. There are plenty of ways to get ahead when you don't have the top product on the market. The smoke-filled backroom meetings may be a thing of the past, but the net effect lingers. This is exactly what went down, according to a Reuters report, when Microsoft (MSFT) had a chat with News Corp (NWS).

Microsoft suggested a relationship with News Corp which would involve the latter's yanking its news sites from Google (GOOG) ... for a fee, of course. This would cost the search engine giant -- which is also a news aggregation giant -- access to some hefty publications, including the Wall Street Journal, the Sun and the New York Post.

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.

Google (GOOG) is letting a few developers peek behind the curtain. The early look the company's new operating system, Chrome, is happening in true Google style: by invitation only. When it's released, which should be in time for the holidays, developers will be able to bang away at an open source solution, tapping an army of volunteers who are eager to work for bragging rights.

The open source version is called Chromium OS, which will hit the market a year before the "consumer" version is ready, which is how Google will be able to tap the wisdom of developers around the world. In a blog entry, Google explained, "This means the code is free, accessible to anyone and open for contributions." The project includes the code base, user interface experiments and some preliminary designs, all of which can be used for ongoing development efforts. To energize the potential base of contributors, Google said that "development will be done in the open from this point on."

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.

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.

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.

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.
