It’s a valid question.
Part of it is that the comments section of our articles on the main page often suffice, and the forum isn’t really needed.
It doesn’t help that I haven’t contributed much lately in two of our “hottest” topics: the quiz and the best looking DVDs. I’ll try and remedy that a bit.
There were some frequent contributors who moved out of Twitch, and there seems to be some form of “critical mass” involved, as beyond a certain point posts don’t generate enough new posts, and topics don’t turn hot anymore.
The opposite happens in the part of the forum that can only be seen by moderators: as our line-up of writers includes people from across the globe, the forum is our best way of communication, and that part is very busy indeed!
