Is Facebook really threatening to sue Mark Zuckerberg? Yes, though the Zuckerberg in question isn’t the company’s young, U.S.-born founder. Born Rotem Guez, the Zuckerberg at the center of the suit is an Israeli entrepreneur who legally changed his name earlier this month. Facebook’s law firm Perkins Coie has actually been threatening to sue “Zuckerberg” since September on the grounds that his social marketing company, Like Store, violates Facebook’s Terms of Service. Like Store is in the business of selling companies Likes for their brand pages. Translated by Mashable, Like Store’s homepage reads: “Are you sad no one’s visiting your …

CNNMoney examines what appears to be the new Twitter. Meaner -- if not leaner, as it’s grown from 120 to nearly 800 staffer in under two years. “The company is laser-focused on two things right now, insiders say: refining its product and making money.” Led by its once-exiled co-founder Jack Dorsey, "It's not cute anymore if Twitter doesn't work," an inside source tells CNNMoney. “Dorsey, say those who have worked with him, is cut more in the Steve Jobs mold.” “He's a relentlessly driven product perfectionist who currently spends eight hours a day at Twitter and then puts in another …

It's ironic that Groupon and Amazon are now using local commerce to set their services apart. Yet, Amazon recently offered customers discounts if they used its price-comparing smartphone app in a physical retail store. “During the one-day promotion, shoppers could have gotten a 5% discount, up to $5 each, on up to three qualifying items,” The Wall Street Journal reports. In response, Groupon this week announced a “Buy Local” promotion that gives customers $10 in Groupon “bucks” if they purchase any of the site’s daily deals in a physical store. To receive the promotion, as WSJ notes, customers must sign …

Just when marketers were adjusting to smartphones and tablets, hardware firms are already preparing the next killer screen. What will it look like? Well, pointing towards “wearable computers,” The New York Times writes: “The ultimate version of this technology is a screen that would somehow augment our vision with information and media.” Likely peripherals of some sort, both Apple and Google are secretly working on projects that will become wearable computers, NYT reports. Google researchers, for instance, are apparently working on peripherals that -- when attached to one’s clothing or body -- will communicate information back to an Android smartphone. …

In other Facebook news, a district judge just ruled that the social network may be sued by uses who claim that showing ads, which friends apparently “like,” violates a California law regarding commercial endorsements. U.S. District Judge Lucy Koh in San Jose rejected Facebook’s bid to dismiss the lawsuit on Dec. 16, “ruling the plaintiffs may pursue claims that the company’s sponsored ads violate state law and are fraudulent,” Bloomberg reports. However, “Koh granted Facebook’s request to dismiss a claim that it unjustly enriched itself with the sponsored ads. As Bloomberg notes, Facebook earns revenue primarily through the sale of …

Facebook knows that serving as a conduit between brands and consumers is a potentially lucrative business. Doing what it can to strengthen that position, the network is introducing a new feature to let business pages receive private messages from consumer fans. “The new communications option, which has appeared for Asia-based admins only so far -- although this could be down to time difference -- is a significant introduction that will allow businesses to interact more closely with customers on the service than ever before,” The Next Web explains. Consumer facing businesses could find the feature especially useful, TNW adds, because …

Don’t expect the current flood of tech start-ups to slow in 2012. In the past few weeks alone, AllThingsD’s Liz Gannes has gotten wind of three new ventures, each of which is out for supreme market disruption. First up, Yelp co-founder Russel Simmons, who left the review site a year and a half ago, is reportedly working on an education project dubbed Learnirvana. “It looks like Learnirvana’s first product, Lentil, just came out,” Gannes reports. “It’s a Web tutor program that helps users learn to read Japanese or the capital cities of the world through constant quizzing.” YouTube co-founder Jawed …

Making a grand entrance, Zynga debuted on Nasdaq Friday morning at an asking price of $11 a share. As MercuryNews.com note, the price was 10% higher than the online gaming company's initial public offering price of $10. The result?

Just when you thought things couldn’t get any worse for Research in Motion, the Blackberry maker said this week that a new line of smartphones -- which were expected to give the company new life – are being delayed until late next year. “It was the latest, and perhaps most significant, setback in a string of product delays and missteps from the company,” writes The New York Times. When they do eventually debut, the new phones are expected to replace RIM’s aging operating system, which should give them performance capabilities more like Apple’s iPhone or phones using the Android operating …

Despite reports to the contrary, Bill Gates says he has no plans to pull a Steve Jobs, and return to the company he once founded. Speaking with The Sydney Morning Herald, Gates said he had made the transition to work full-time at his Bill & Melinda Gates Foundation "and that will be what I do the rest of my life.” Explained Gates: "I'm part-time involved with Microsoft, including even being in touch this week to give some of my advice but that's not going to change -- the foundation requires all of my energy, and we feel we're having a …
