If you Improve forum you improve community thus improving the game.
I think BB has one of best forums out there. Noone has Sneak peak that lets you know which of your messages have been answered to. Other forums' option is "follow this thread", but you still have to read through all consequent messages to know if anyone replied to you.
This forum shows you how many messages have been posted in a thread since you left. Other forums notice you only of when there are new posts, but not how many.
When you click on a thread, you start with the first message you didn't read yet from the last time you were there instead of starting from beginning.
Etc. etc. If you payed more attention to details or cared to compare this forum to other, you'd see lots of differences. Instead you just bash something without even thinking why.
Average BB user does not read the forum? That's because forum is not an integral part of BB. Matches and training are. This doesn't mean forum is useless, yet you made that connection which is very unfair to forum developers.
