It appears to me that SO is inundated with questions which can answered by a trivial google search or by perusing the documentation. I'm not talking about 1 or 2 out of 100, but like 20-25% of the questions are of this type. My feeling is that SO is devaluing itself by allowing these questions. If SO wants to continue to be a truly "expert" forum it might be prudent by following the custom of some language centric irc channels and not tolerating questions that can easily be answered by some effort in reading or searching on the part of the questioner. Continuing to allow these questions dilutes the quality of SO and may even sink it to irrelevance.
The point is to build a database of Q&A so that Google will always find it here.
The problem is that Google doesn't have ANY answers. It sends you to other sites with answers. SO wants to be that site.
I think it may have been in one of the podcasts (sorry, can't remember which) and Jeff/Joel spoke about how they want SO to have answers to questions of ANY level, even super-noob questions ('What is a variable?' type stuff) even if they have been answered previously on another website/resource.
Edit: I was being sarcastic!
Google can find anything so why don't we just stop using SO?
