What I remember is this:
Around 1998 or 1999, hockeyboards.com was the biggest and best place to go to talk hockey on the net. Much like this site, it was organized with team boards, a league board, an off-topic board, etc, etc.
They then merged with a larger sports site called fanhome.com and upgraded the board and probably became even more popular for awhile. However, after only a year or so, they again merged with another sports site, scout.com (I think).
At that point, it was too many changes in too short a time and the site's popularity died almost overnight. It was a real lesson in how fickle internet users can be, really; it went from top dog to being a ghost town in no time.
At any rate, a lot of the users (including me) who were at that time dissatisfied with fanhome/scout migrated over to HFboards.com. That was around 2002 or 2003. It was that influx of users that really boosted HFboards to where it is now. Whereas, before that, it was a very minor player in the hockey messageboard community.
I still recognize a number of usernames here from the hockeyboards days.
