GFY has a very high signal:noise ratio. It’s good for launching programs, and buying sig traffic, but other than that it’s always been more about talking shit than shop. If you’re a newbie however, GFY will only cause you pain 
I’ve always liked:
http://bbs.adultwebmasterinfo.com/
http://askdamagex.com/ is also good.
http://bbs.porncity.com/ – has been consistently strong for years
For a newbie, Ynot and cozyfrog will both be nice to you.
http://www.xbiz.com has also been goood.
If you want to find something in particular, use BoardTracker http://www.boardtracker.com . It was originally started to spider adult webmaster boards.
Hope that helps.
