Even the video game forums i looked at as a kid are full of college age and up people for the most part.
I think it goes in cycles. You had usenet, AOL chat rooms (who does that now, outside of pervos trolling for jail bait?), then you had forums, and twitter/reddit, then instragram, and now...well, not sure what it is people do. I'd bet that most of us here are between the ages of 29-45. There are some people outside of those ages (iirc, there was the older gentlemen who was in his 70's on here...whatever happened to him?), but mostly it's not full of younger posters. And thank god it's not.
Most of them are too illiterate to write a coherent sentence, so they avoid places that utilize typing.
Yeah, i'm a few years younger than the age range you mentioned, as well as several posters on here, but i'm thankful for that. Most people my age are still really stupid, and this place would be even more full of trolling than it is.
I love you sly. hahaha. I was trying real hard to toe the line, but alas, I got my first SPD edit. I will wear the badge proudly.
