As viewers increasingly shift their focus to mobile devices, Facebook is positioning itself as a video platform on par with any TV network. So Facebook’s COO Sheryl Sandberg told Re/code before the company’s earnings call, on Wednesday. “In terms of replacing TV, we certainly don’t think we’re going to replace any one medium,” she said. “We do think that eyeballs are shifting, not just from TV but from a lot of other formats, to mobile. And we are positioned very well to not just participate but to lead that shift.”

Twitter is reportedly ready to hire Natalie Kerris as its new communications head. “Kerris is well known in Silicon Valley for her job as one of the top public relations and communications staffers at Apple,” Re/code notes. “She was in the running for the top job at the tech giant, which went to Steve Dowling, after the departure of Katie Cotton.”

Kevin Weil, most recently Twitter’s VP of product until he left the company this past week, has reportedly already found a new gig: head of product at Instagram. “Weil was recruited by Instagram for months before announcing his departure from Twitter late Sunday night,” Re/code reports, citing sources. Peter Deng, Instagram’s last head of product, recently left for Oculus.

For all its faults, Twitter still has a few things going for it, and strong sales growth in particular. “Even as Twitter’s user growth has flat-lined in recent months, the company has continued to increase its sales at a healthy clip,” Bloomberg reports. “In the three months ended in September, revenue reached $569.2 million, a 58 percent increase from sales in the period a year earlier.”

Periscope is partnering with GoPro so users can broadcast to their followers from the action cameras. “The integration … allows Periscope to recognize a GoPro whenever one is connected to an iPhone,” The Verge reports. “The integration raises interesting possibilities for surfers, skiers, snowboarders, and other athletes.”

Google has officially shut down its Glass social media accounts. “This doesn’t come as much surprise as plans to bring Glass to the consumer market (at least by that name) have long been abandoned,” 9To5Google reports. “Google’s front for representing the device in the consumer eye may be gone now, but in the background Glass lives on under the umbrella of Project Aura.”

Expanding its use of Apple’s 3D Touch, Facebook is adding pressure-sensitivity to users’ timeline. As Slash Gear reports: “The added functionality, which takes advantage of the new touchscreen technology Apple introduced with the latest versions of its smartphone last year, builds on the Facebook app for iOS’ 3D Touch-enabled quick actions from the homescreen.”

Facebook is open-sourcing Transform -- software designed to stream users’ 360-degree videos more efficiently. “At Facebook’s size, the company must do what it can to deliver content to many users quickly and cut down on file storage space when possible,” VentureBeat reports. “After all, the content does need to be stored in Facebook’s data centers.”

Location-based social network Yik Yak has launched a Web client. “The company has been working on the web version of the app for the past few months in a closed beta, and is now ready to unveil it to the public,” TechCrunch reports. “To get going on the web, users simply add the same phone number they use with the mobile app.”

Veteran social network Friends Reunited is calling it quits. “Launched in 2000, it boasted more than 23 million users at its peak, but now one of the original founders of the site say it is now only used by a ‘handful of members,’” The Daily Mail reports. Among the FR’s current 10 million registered users, most of their contact information is out of date, according to its founders.
