I know a handful of people that have reasonably high IQ's (above 130 or so). Many of them also have infantile senses of humor, short attention spans, and live with their parents well into their late 20's. It's been said a few times already, but raw processing power doesn't necessarily say anything about a person's maturity, rationality, or interests. What could work, however, is a Maturity Captcha! When a user submits a story, (s)he's presented with a series of snarky headlines and/or lolcats and asked "Do you think this headline is funny?" or "Isn't the kitty clever?". Or maybe word problems: "Jack wants to buy a Wii, but he only has enough to pay his rent. Should Jack buy the Wii anyway?". An answer of "yes" to any of those would have some negative repercussion (instant user ban, posting ban, lower karma, public humiliation, etc). Getting past the captcha would be ridiculously easy for 14-year-old geniuses, but at least there will be a constant reminder of exactly what's unwelcome. On the other hand, aggressive censorship could take care of the chaff pretty effectively. After all, the problem is, generally: "how does a small ruling-class of individuals shape the growth of an entire community". There no sense in deceiving ourselves about what that means: elitism, exclusivism and in some senses, totalitarianism. But hey, if it's YOUR community, do whatever you want!
