I started a board game society at my university at the beginning of this academic year and we had some not-inconsiderable interest in D so I - having never played it myself - was obliged to support someone to DM a few games and see how it went.
A few months later and our party has grown to 11 people, plus DM, who meet up once a week (as well as again the next evening for board games) to play an ongoing 3.5 campaign with inventive scenarios and some really, really great roleplaying - the kind of D&D sessions which I imagine we'll still be talking about years later. We've also got several other people interested in joining in for the next story arc, a couple of people wanting to DM their own D&D games, and we're in the process of starting a new GURPS campaign to run alongside.
Certainly D&D probably isn't as popular as it used to be, but I really have to take issue with the idea that 'few people born after 1990' would be interested - if anything it's one of our biggest membership pulls. There are so many people out there who, like me, have never tried it but - despite any bad press they've heard (mostly to do with uber-geeks; you know the kind) - really would like to try.
They just need a gentle nudge in the direction of a group who's willing to have them.
