A shame that pornography, drugs and gambling are the best bets to gaining any traction for something like bitcoin, but don't look a gift horse in the mouth eh?
Pornography tends to push edge stuff. And even helps the adoption rate of many of those things. Just looking back. Photography, Video, VHS/DVD and Bluray, Internet/WWW. Seems they always in front of things before 'mainstream' does. So it's not always such a 'bad' thing.
