This has been said elsewhere, but outside of /b/, 4chan is quite a normal board. I don't read the whole thing, but in my experience, /fit and /diy are fairly civil and often work-safe. /v seems about as good as any video game nerd discussion can get, especially since Quentin and his Diamond Dogs have been rescuing everyone.

I have been very surprised to not see very many people taking up 4chan's self-serve advertising. The audience on 4chan is pretty clear: video gamers, lovers of Japanese culture, artists, trustafarians and paranoids. They spend money on games, computer equipment, plastic figurines, art supplies, costumes, body pillows, music, camping equipment, tools and knives.

If you're curious, DailyDot published a lengthy profile of him a few months ago that wasn't bad

Are you referring to 4chan? If so, I think Twa^Hitter is far worthier of that title.
