Hey kuji. ;-)
I think we were all very different. Things used to seem so much bigger - and I guess they were at one stage! I remember when I'd log into OB each day and find dozens (and, at times, well over a hundred) new posts across the forums. It really did feel like OB was a big community, but not as painfully big as a 4chan or something like that.
As it is, I never really got into message boards much after OB. I post occasionally on AppleInsider, but that's about it. I used to post on Steam User Forums, but now the Half-Life area has died down so much that I don't really bother anymore.
OB was really the only place that had that really unique mix of topics (everything from political debate to video games to RPGs). :)
It's good to see some people still around. Although, there are a few people who just disappeared and I've always wondered what happened to them...
