Well, the channel is growing. We have six regulars in the channel in the evenings. When I wake up and check my logs, though, I've noticed people coming into the channel and then immediately leaving two minutes later without saying anything.
If you're interested in playing some pick-up games, the IRC channel is a great place to find 'em. Just don't base your opinion of it on an empty channel at 3am. If you come in and there are people online, say 'Hi' and stick around for a few minutes.
