This thread has grown very interesting.
Most of this is my fault, as the Referrer Contest has been a disaster.
"General Chat" is great, inside a community. The problem is that many of the new folks from the Referrer Contest are not integrating into the community, they are spamming it.
They are making 10 quick posts each and leaving. Often these posts are off-topic and written in a manner that resembles children's SMS messages.
So, this is my fault and it's my responsibility to implement a solution. That's the next thread I'm going to visit...
But.... aside from the Referrer Contest aspect of this... I am very interested in the discussion which this event sparked. I've had quite a few people contact me privately also. I am certainly learning a lot about what people are looking for in a webmaster forum.
