Add a custom search option that can filter people by reputation level, or by question to answer ratio.

I want to answer questions from people who are able to Google, and who are able to answer questions.

Another thing: add a custom search option that can find tumbleweed questions. I asked about it here:

http://meta.stackoverflow.com/questions/14738/tumbleweed-que...

But Jeff thought it was already implemented, when it's not. The advanced search finds questions with a minimum number of views, not a maximum number of views.

You may be able to implement this yourself using the data explorer:

You could do that as a direct step towards finding the questions you desire, as as a rhetorical move towards getting it implemented in SO.
