We do.Me in real life. I'm pretty sure that's most of us, in real life, if I'm being honest. Post-by-Post roleplaying is like, maybe five steps for D&D. Actually, don't we have a D&D style board? Pretty sure we're pretty far in the nerd pit.
Oh, I'm fully aware. I play D&D in real life, but it doesn't exactly mean I'm swimming in hotties. -looks over at massive pile of DMing work, which includes everything from encounters to villain stats and custom classes, then sighs-We do.
And you'd be surprised how Social D&D can be. :P
Remember for forum roleplaying you just need to find some (and in many cases only one) online peep to play with.
D&D you often need to find a whole group of people IRL to play with weekly.
