And you're doubly right about the forum demographics. While the average gamer is older, they're certainly a sort of "silent majority."
That's true. Everyone I knew was really into gaming back in the day (I'm 44, fwiw) and many still are, but they're extremely reluctant to go online for some reason: a few are becoming active on the likes of Facebook but it's very unusual to see them on forums, even the people I know from the computing course I took at university. No idea why, I do try to get them involved now and again but they're stubborn buggers. I feel quite unusual amongst my peer group as I'm one of the few who's actually quite active online.
