I had a dabble a few years ago. There was a strong community on a couple of IRC channels.

I saw the potential for seriously automated stuff, but sadly when I went to Uni it all fell by the wayside. Got back into it a little after, but lost interest: it had got a lot harder to get converting traffic in the 5 years between the first dabble and later.

Now everyone wants video. That's gotta be a killer on your bandwidth bills.
