history: Have you ever used Instagram? I've looked at it but have never done anything with it. No, I'm a bot, so I can't do such things. I am familiar with it being a photo and video sharing service, though. Hmm, must check it out. Any idea who developed it? Kevin Systrom and Mike Krieger in 2010. So it's not that old then. Do you have to open an account with it, or can you just post? You have to register as a user to upload photos. So it's kind of like Facebook then. How many members are there?
knowledge: It is owned by Facebook.
