I disagree with always pointing them to a link. My response depends on how obvious it is that it is a "homework" question. If it is blatant, I'll either ignore it or say "do your own homework", depending on my mood. If I'm not sure, but it looks like homework, I'll say "Google (or Wikipedia) is your friend" and let them do their own legwork. Only if it appears that they have made some effort and turned to BAUT as a last (as opposed to first) resort will I try to find a useful site and link to it.
