@mangeons – You are a pretty mature 13 year old. I’ve seen a lot of young kids who come in here and just expect the world to revolve around them, or they ask such menial questions that remind us of when we were that young. But you are not such a person. Raising the age limit of the site would deprive us of people like you, the responsible young ones, and would somehow give the impression that older people are more mature than younger people, which in many cases is laughably false!
Age limits are arbitrary and not a good evaluator of maturity or ability to contribute to a community. And sometimes being old and wise isn’t the best thing – you for instance have the best knowledge about 13 year old culture (what words are cool, what actors are totally not cool)! Everyone has something to provide at their age that no one else can provide. Without a variety of folks, we’d be a 10,000 piece puzzle with many pieces missing.
