I'm not, but the PR guy at work still does most of his communication there. It's because that's where both news and rumors spread. If you're not active, you come back and suddenly everyone is convinced you've done, or have plans to do something horrible. You basically have to sit there and deal with the abuse, just in case you actually have done something horrible. He isn't a particularly happy guy.
I used to post amateur photography there. I do still miss the community. It was far more engaged and supportive than anywhere else I've found.
