Are American teenagers obsessed with Instagram?

[Que sera, sera.]

I don't think it's strictly an American thing. Some of my favorite people to follow on instagram are from other countries, and they upload ALL of the time. One from Canada, a handful from places in the UK, two absolute favorites from Queensland, and on the 'popular' page, I always see Korean uploaders. Many aren't even teens, but adults recording their jobs, their children, and exciting life events. A lot of teenagers use it to upload annoying 'selfies' and their Starbucks drinks, but I don't think they're the majority, if you actively look for more quality people to follow. It's like a visual blog.
