Planning a ridiculous evening? Thanks to the Social Media Sobriety Test, it'll be somewhat harder to offend a community of over 500 million people when you get home. To get online at a time you've set as off-limits (say, after 11 p.m. on St. Patrick's Day) there are certain logic or agility tests you must complete. If you can't, the app will tell everyone that you are too intoxicated to post right now. Which is possibly even more embarrassing than posting.
