Internet Groups?

[Sarah]

So I like fashion and photography and i would LOVE to join a group of people with the same interests were we could chat and post things, I'm in one on facebook right now but i found it through a friend and i would like to be in one on my own. But idk where to look, im a highschooler so if anyone has any ideas that'd be great :*

What about tumblr? You don't really join a group, per say, but you can have a specific type of blog, follows blogs similar to your interest and communicate with people.
