Does Facebook have a sharing problem? If it does, the social network is considering ways to increase the amount of stuff you post, especially pictures and videos. The Wall Street Journal reports that Mark Zuckerberg & Co. are working on a standalone camera app with the aim of helping you create and share more content. WSJ's sources indicate that app has two prominent features: still photos and the ability to broadcast live video footage quickly. With the popularity of sharing via Snapchat, and Facebook's on-going push for live video, it's easy to see why the company would take a stab at a new app.
