Inclusionism vs. Deletionism has been a philosophical debate at Wikipedia for some time, and has already started to be discussed on this site during Stack Overflow's very short life (see here, here, here, and here).
The main question in the context of Stack Overflow seems to be whether bad content (non-programming related, One True Way questions, etc.) should be moderated by some authority or should naturally sort itself out of view based on user input.
Jeff has tended toward the Deletionist camp in his blog, but so far users aren't even able to delete their own questions on Stack Overflow. A clear direction on this issue will probably be very beneficial to future design decisions and also give the community a better idea of how to address inappropriate questions and answers.
