Congress is too old and clueless to ask smart questions. Zuck's acting all Lore from Star Trek. FB stock is up just because people keep thinking they'll beat this shit, which they won't.
They absolutely will beat it. Facebook isn't done until there is a direct competitor, not "an alternative". Plus, they own Instagram and Whatsapp which are becoming increasingly valuable properties.
Just wait till earnings. They are going to beat, and anyone not onboard is going to feel the full power of FOMO.
