My daughter, who's 7, has asked me if she can have snapchat. I've never mentioned it to her or even used snapchat, so she must have picked it up at school. I don't even know if she knows what Facebook is.

Likely. My nieces (ages 5 and 8) LOVE the filters on Snapchat. We call them "funny faces". Snapchat really captivates young people.

Yep, I said what I said in the OP because my sister (11) asked me if I had snapchat (to which I replied no, but then grudgingly signed up).

Had she not been using it I would have written it off as confusing UI and "what's the point."
