ASHA has several discussion boards but I have never seen much traffic on them at all. I know that this is one of the first results on google when one searches audiology forums. That is how I found it. There is also hearingaidforums.com. I have not been on it a whole lot, but that is very consumer driven with some professionals on there. I have only commented on a few posts there and don't regularly check it. I agree Dusty, I think it is a lot of listservs. I was on the Educational Audiology Association listserv for a while and found it to be somewhat interesting. I also think there is an ADA listserv, but I'm not positive on that.
