Honestly, this is the first time I knew someone via the internet that has passed away, and you know what? It's actually very sad. I mean, I never really knew him per se, but everything that he did and said was a good contribution to the forums.
Actually, I had a friend pass away from cancer just a few months ago and, needless to say, the fact that he was (by outside definition) labeled an "Internet friend" did not make his passing any easier or any less tragic to me.
This is a very sad day. My thoughts and prayers are with Brendon's family through this very difficult time. He will be missed terribly ... he was a very unique individual and, like Spire said, this board is going to suck all the more without him.
