/d/ can be a pretty nice community considering the focus. I don't know if I can put into words the effect it had on me, but in retrospect it seems to have been mostly positive.
Thanks for running the site for so long, moot. It's great fun.
/u/'s always been a pretty nice community too, and is unlikely to offend anyone except social conservatives. (/y/, on the other hand, has always been fairly hostile. Don't ask me why.)
