Perhaps most importantly, Facebook is now offering wine and champagne. And Facebook is making sure it's doing this category right—it's partnered with 16 different wine makers. (Yes, Facebook has all sorts of restrictions to make sure it's not sending alcohol to minors.

Taking Away Facebook Users' Vote
Facebook also announced on Tuesday that users will no longer be able to vote on how the company can share personal data, thanks to the lack of response to its recent site governance vote.
The vote drew nearly 700,000 responses. Of those, 588,803 opposed Facebook's proposed changes, which included taking away users' right to vote. Nearly 80,000 people supported the changes.

Perhaps most importantly, Facebook can share data between Instagram, which it owns, and its core network.
