I do have to say that the first time I went looking for help, I went to the IRC channel, that had 7 people in it, all of which were idle. The IRC channel would be great for answering quick questions for new users, and joining a mailing list does require a bit of commitment. For the more in depth questions, people should be directed towards the mailing list. A active IRC channel would encourage more collaboration between users and be more welcoming to new users with simple questions.
I think we should encourage more people to join and participate the IRC channel.
