Welcome to this morning's edition of "First To Know," a series in which we keep you in the know on what's happening in the digital world.
Today, we're looking at three particularly interesting stories. Facebook beat earnings expectations for the quarter, clearing $1.58 billion in revenue. Twitter has enhanced its multimedia experience with a pop-up gallery for large photos. Furthermore, its media galleries now include videos from all of Twitter’s partners — notably Vine, Youtube and Vimeo. And while we're on the subject of Twitter, a statement on gun violence from Arizona representative Gabrielle Giffords sparked both positive and negative reactions on the social network.
Check out the video above for more on these stories.
