I disagree. 20 rep is about 5 or 6 good answers, depending on how lucky you are and how popular your technology of choice is. How many people are going to put in that much effort just so that they can use a chatroom?
If they aren't willing to answer or ask a question to use a chat room structured around answering and asking questions, I think I'm okay with the situation.
I'm not saying it's not too much of a hassle -- of course that's up to you.
