A lot of people are from the original 196. But if you're talking about the micro celebrities, I haven't seen any of them, and kind of don't expect to, maybe some day, but I doubt it.

I mean I'm from the subreddit and I think most people on here are from there. Recently even made a Spronkus post that got some attention. I'm not someone whose nickname you'd know though, I wasn't actively posting very much on Reddit.
I don't think you can follow people here though.
