The bot revolution is happening fast for Facebook. After launching third-party bots in April offering everything from forecasts to your boarding pass, the social network says there are now more than 11,000 bots active on Facebook. To celebrate, Facebook is adding a bunch of new features that could show up on your favorite bots soon--if developers enable them, that is. One big problem with bots is they feel a little antiquated. Many of them will only respond to certain commands, which can make the whole experience kind of tedious.
