Many answerers don't know a lot about the subject at the time of reading the question, but get intrigued and just start reading about it. It's pretty fun actually, you get to learn it yourself first and then hone your writing skills by distilling the information into an easy to read comment.

I read of a study which concluded that teaching others immediately after learning something new is the most reliable way to retain the information. Personally I believe it is too!
