Digital investments are critical to turning “Meet the Press” in what NBC News president Deborah Turness envisions as a “7 days-a-week source for politics and beltway buzz.” And, as NBC News SVP Alex Wallace tells Huffington Post, host David Gregory is key to ramping up the show’s digital presence. "We're doubling down on David Gregory right now," Wallace said. "This whole digital brand is being built around his strengths." 

More than ever, Marissa Mayer wants to get Yahoo out of its search pact with Microsoft. Sources tell Kara Swisher, she told Satya Nadella as much during a recent powwow with Microsoft’s new CEO. “Mayer’s basic message to Nadella has remained the same as it has been for a while now -- Yahoo wants out of the deal, and sooner than later,” Swisher writes in Re/Code. Meanwhile, Yahoo is aggressively developing its own search strategy. 

Turntable.fm founder Billy Chasen is hard at work on his latest venture: a new app named Ketchup, which helps social media users engage with their various contacts at different frequencies. For instance, "My girlfriend wants to know when I’m home, or at the office, or at the coffee shop, but blasting that out to my whole Twitter following would annoy people," Chasen tells The Verge. As The Verge explains: “Imagine a status update you can leave for people … but done in a way that is mobile native and lets you easily control who sees what status.” 

Users of Google’s Android Search app can now access their phone’s camera and video features with a word or two. “It’s an incremental change, but points to the possibility of further enhancements for marketers,” Marketing Land’s Martin Beck notes. “Either tap the microphone or say, ‘OK Google,’ then ‘take a photo’ or ‘take a video’ and the camera app launches in the preferred mode.” 

Getting a little nostalgic, Twitter is rolling out a new tool that helps users find thei first tweets. “The social-networking service is sharing the service with fans in celebration of the Twitter’s eighth birthday,” Time.com reports. “The tool is simple: plug in your username and get ready to cringe … Or at least get ready to see how excited you were to tweet about the contents of your lunch in 2009.” 

Friendster founder Jonathan Abrams is giving the world another social news service named Nuzzel. “Instead of using machine learning to understand user interests, or summarizing the news with human editors, Nuzzel does something simpler,” TechCrunch reports. “Once you’ve signed in with your Twitter or Facebook account, it will show you a list of the stories shared by your friends (along with their commentary), arranged either chronologically or based on whatever’s been shared by the most people.” 

From the makers of Rather, which edits out “the stuff you hate on Twitter and Facebook,” and incompatibility detector “Hate with Friends,” comes Cloak -- an “antisocial network” that uses social check-ins and other geo-location data to help people avoid the ones they hate. Chris Baker, Cloak cofounder and former Buzzfeed creative director, “seems to specialize in vaguely misanthropic apps,” The Washington Post notes.  

Just so everyone is clear on the matter, WhatsApp founder and CEO Jan Koum says selling his company to Facebook won’t affect its data-collection policy. "Make no mistake: our future partnership with Facebook will not compromise the vision that brought us to this point," Koum explained in a new blog post. “WhatsApp doesn't currently collect information about its users' name, email address, home address, birthday, location, employment or interests,” The Hill’s Hillicon Valley blog reports. 

Creepy as it sounds, Facebook has developed a program that can correctly identify human faces with over 97% accuracy -- about the same accuracy rate as the average person. “It demonstrates the power of a new approach to artificial intelligence known as deep learning, which Facebook and its competitors have bet heavily on in the past year,” the MIT Technology Review reports. “This area of AI involves software that uses networks of simulated neurons to learn to recognize patterns in large amounts of data.” 

Raising speculation about Twitter’s global expansion plans, CEO is making his first visit to China to meet with Shanghai government officials, academics and students. “Twitter, which has been blocked by Chinese censors since 2009, described the trip as a personal tour for Costolo,” Reuters reports. “Unlike at Facebook Inc, whose CEO Mark Zuckerberg is a frequent visitor to China … Twitter's senior management has played down the likelihood of seeking a license to do business there.”
