What Social Networks Are You On?

Here at Business Hacks, we've noted the marketing potential of Facebook; questioned the overall purpose of LinkedIn; looked at using Twitter for branding and PR; and checked out how businesses leverage lots of other social networks as well.

Because we're not actually sure where "social networks" end and "online profiles" begin, we'll stick with our big three for this poll. So let us know: which sites do you maintain an active individual profile on? (And let us know which one you like best and what hot new networks we're missing in the comments.)
