I think when most of the forum problems are solved /the spam, bumping bots, account farmers, bounty/signature abusers, etc./ people will turn back to discussion stuff, and look away from Meta, but as long as there are problems /and we had quite serous ones solved lately/, the attention will be here.
What are the "quite serious" forum problems that were resolved that you are referring to? You mean things like account farming or something else? Are they solved or just the incentives changed?
