To put it another way: Can we assume that someone who asks a question on Super User has tried to find the answer elsewhere first? For many (most?) people, the first step in finding an answer to just about any question is to google. If an answer can be found easily on Google, does that make it too easy for Super User?
Do we want Super User to become the first place people go for answers to questions related to computer use? Does Super User 'compete' with Google in that sense?
Certainly, the quality of the answers on Super User often exceeds what can be found elsewhere, and the idea of Super User being more relevant than Google for finding answers in itself sounds appealing. But in practice, if Super User becomes everyone's first stop for solving computer use problems, we're going to see a lot of questions that are incredibly basic. Is that a problem? Perhaps not.
So my question comes down to this: are there questions that are too easy for Super User? If so, how should such questions be handled? If not, then it should be interesting to see what happens to the quality of Super User questions as the site becomes more popular. If the Super User moderators spend all their time reframing Google search results in easy-to-consume packages, the task might grow wearisome.
