It was always a small community to begin with. Other BL forums have suffered just as dramatic a decline. It's just that a 75% drop in usage for a forum with several hundred people still leaves you with a somewhat vibrant community (as is the case with boychat) whereas that same drop in a forum that only ever had 10-20 active users at a time leaves you with just a few who post anymore. The age of bustling internet forums has come and gone it would seem.
