That's an interesting idea. If, for instance, there was a window of time for people interested in a show to come together to discuss the latest episode (assuming the episodes aren't just dropped all at once), then I think it would be an interesting place to visit since everyone is there for the very same reason and there's something of interest that happened recently that would focus the discussion.
I will say I did visit the site months ago and found that just hanging out with random people wasn't that compelling to me. In the early days, it was fun because it was new and there was a lot of energy, but after that, you really do need something to bring you back day to day.
