Today we launched Social Pulse, our new social media hub on Reuters.com designed to show you the most talked-about news, companies and influencers across the Web.

The first thing you’ll see on the page is the news most popular in Reuters social network. Our journalists and official Twitter accounts follow everyone from Nouriel Roubini and Jenna Wortham to John McCain and Rachel Sterne, and these are the stories being talked about by the newsmakers we follow. The technical detective work is done by Percolate, a social news service that powers Felix Salmon & Ryan McCarthy’s Counterparties.com.

Next you’ll see our stock sentiment module, featuring opinions from hundreds of thousands of sources captured and curated by WiseWindow. WiseWindow is not simply a keyword analysis tool, but a complex system that uses statistical techniques and natural language processing to deliver data that is not only real-time but predictive as well. The chart is populated by share-of-voice readings, so depending on which companies are being talked about most that day, it will adapt.

Below that is the Reuters & Klout 50 where we rank America’s most social CEOs. We predefined a list of almost 100 CEOs who are active on Twitter, tweeting in English, and have a handle separate from their company’s (sorry @zappos!). The top 50 are shown here every day based on their Klout score, the standard in measuring social influence. Who made the list but not the top 50? Alisa Miller of Public Radio International, Mark Bertolini of Aetna, Perry Chen of Kickstarter, and Angela Ahrendts of Burberry are just a few of the CEOs whose influence in the boardroom isn’t matched in the social media world (yet!).

Just as important as these partnerships is the wonderful work being done on social networks within Reuters. Anthony De Rosa, who does not like it when I brag about him, is our social media editor, chief liveblogger and tech video journalist. He has been called the “undisputed king of Tumblr” by the New York Times, named one of NBC New York’s top 20 people to follow on Twitter and is liked by Anthony Bourdain (which may be the most impressive feat of the three). If you’re not already following him on every social network possible, this page will show you how to. It will also show you what Anthony is liveblogging, what video he’s just done, etc., so you can keep up with him on and off the site.

The least suspenseful waiting game in Silicon Valley is now over, thank heavens. Facebook, which began as a decidedly private Harvard hangout, has begun the process of going absolutely, totally, unabashedly public.

Facebook filed for an initial public offering with the SEC Wednesday, which means we have the first raw glimpse of its financials. Advertising makes up 85 percent of its $3.7 billion in annual revenue. And it took in $1 billion of income in 2011. For more of the best data points, see my colleague Anthony De Rosa’s rundown.

Facebook is synonymous with the Internet in many ways: It boasts more than 10 percent of the world’s population as active users and has realizable ambitions to be the preeminent vetting service on the Net, making a “Like” as powerful and capricious as Caesar’s opposable thumb.

Just a few months after lining up $33 million in funding for his enterprise-software start-up Domo, Omniture founder Josh James has raised another $20 million, this time from Institutional Venture Partners.

“This is a pretty straightforward investment thesis,” said IVP general partner Todd Chaffee. “It’s called Josh James.” Chaffee invested in web-analytics business Omniture, which James sold to Adobe Systems for $1.8 billion in 2009, so he is familiar with James’s drive.

James’s new company, Domo, offers business analytics that can handle large amounts of data across different types of platforms. He’s selling it as a service, meaning companies can skip hefty up-front licensing fees in favor of pay-as-you go plans.

Sports network ESPN is forging ahead with plans for more 3D television programming, despite the fact the technology is moving slowly into homes.

ESPN President John Skipper, speaking at a conference sponsored by the Wall Street Journal’s All Things Digital blog, said the Walt Disney-owned network would produce up to 150 programs this year in 3D. Skipper acknowledged 3D television is “not a mass phenomenon” but said “with most things, there’s disappointment toward adoption before a rush to adoption.”

For ESPN, which moved quickly into mobile and now commands 70 percent of the market for mobile sports programming, “we want to be leaders” in new technologies. Skipper said ESPN is “getting pretty close to a single truck and a single set of equipment” to be able to produce shows in “5D” – 2D and 3D formats shot at the same time.

Mark Pincus, the CEO of Zynga, isn’t pleased with reports that Zynga is ripping off games from small developers so he is doing something about it–wielding his pen to write passionate manifestos to employees invoking Silicon Valley greats like Apple.

After a game developer accused Zynga of copying a game called “Tiny Tower”,  Pincus sent a 60-line memo to employees to make sure his flock knows Zynga has done nothing wrong, (the memo was leaked to the blog VentureBeat and later obtained by Reuters).

“Google didn’t create the first search engine. Apple didn’t create the first mp3 player or tablet. And, Facebook didn’t create the first social network. But these companies have evolved products and categories in revolutionary ways.”

Neil Young wants a convenient digital device to play music — like an iPod — but with higher-quality sound than consumers hear now with digitally compressed files.

The rock legend — whose ‘Heart of Gold’,  ‘Old Man’ and many others are still top-sellers on iTunes — said he had discussed the idea with late Apple CEO Steve Jobs, and that he and Jobs were working on the issue before he died.

Although Jobs was “a pioneer in digital music and his legacy is tremendous, when he went home he listened to vinyl,” Young said on Tuesday at a conference sponsored by the Wall Street Journal’s All Things Digital blog. “You’ve got to believe if he lived, he would have done what I’m trying to do,” Young added.

There is nothing more infuriating than a slow mobile connection. With people bringing their own devices to  workand everywhere else, wireless networks will be working hard to accommodate the mobile traffic flood.  

Here’s where Cisco comes in: On Tuesday, it unveiled a wireless access point called the Aironet 3600 Series, which can increase the speed of connection by up to 30 percent on any kind of mobile device no matter how weak or strong the network is. 

According to Cisco, it is the first company to offer access points with four antennas and three spatial streams. What does it mean?  Essentially more people have more range to use their devices, even if there is more traffic.

Looks like social media users are getting twitchy about their online privacy rights.

Days after Google made known its decision to establish a common privacy policy across  its scores of products,  a chain-message of uncertain origin began circling on the Internet, claiming LinkedIn had quietly changed its own policy on the treatment of user data.

The chain message — which contained step-by-step instructions on how to opt out of this supposed new policy — took on a life of its own, ricocheting across Twitter and spawning numerous discussion and email threads. It suggested LinkedIn had given itself the right to use personal information and photos in ads — without notification .

Helen Gurley Brown, the 89-year-old former editor of Cosmopolitan magazine and author of “Sex and the Single Girl” is donating $30 million to Columbia University and Stanford to fund a media and technology institute.

Columbia will pocket $18 million while Stanford’s Engineering School will net $12 million. Columbia will use $6 million to build a “highly visible signature space” at the journalism school’s building in New York. This marks a record donation for the journalism school.  

Apple board-member Bill Campbell will advise the new center along with Hearst Corp CEO Frank A. Bennack, Jr. The donation is in honor of Gurley Brown’s late husband David, the famous producer of classic movies such as ”Jaws” and attended both schools. Gurley Brown, who was dubbed “the original Carrie Bradshaw” by the New York Times. edited Cosmo for more than three decades.
