I've hardly been in the philosophy section, but from what I've seen here most people are teens or, at best, college age. If you look at a lot of the questions here, it's just a lot of frivolity in this section or people whom I think just want attention really badly, always talking about how they're considering suicide and their self-esteem. And those same people, plus a few others, answer the questions, as well. They've made this section way more watered down and trivial than it should be, and I really don't want people who do feel they need help to feel bad at that comment but it's just true. But younger people, or most of them, aren't that interested in philosophy.
I think Yahoo Answers really needs to create separate sections for adults and then again for younger people. Every site I've been on that has been geared towards helping people, when there are a lot of young people it just ruins it.
