Hi, maybe I won't spend hours a day on Wikipedia. As I don't have huge amounts of time to contribute, I won't spend a lot of time adding content. My interest is in improving articles which already exist and guarding against vandalism and tendentious editing.
The Reference desk is for questions about life, the universe, and everything (other than about Wikipedia). It's a virtual version of the reference desk at a library. Wikipedians are very knowledgeable, and if they don't know the answer, they can probably find it pretty quickly.
