Which type of person are you?
In my time using Yahoo! Answers, I have noticed that the forum attracts a very interesting range of people, and they can all be divided into a few categories...
1) People who actually have real hands-on knowledge about what they're talking about, like doctors, or chemistry teachers, or authors (this is a very small minority)
2) People who don't necessarily have direct knowledge of what they answer, but research it first and provide reasonable responses with sources
3) Wide-eyed political junkies from all regions of the political spectrum (These ones can be particularly nasty, often resorting to trolling and name-calling, etc)
4) Teenage girls asking each other if they're pretty or pregnant, and a smaller but equally active population of males doing the same
5) Wanna-be comedians/point-hunters who answer/ask completely randomly and add absolutely nothing to Yahoo! Answers (I, for one, would fall under this category)
6) Kids trying to get other people to do their homework for them
7) People that are just plain bored and ask questions for other bored people to answer (and vice versa)
8) People who try to escape my inescapable categories of Answer users
