I am ambivalent about this issue. I do find it interesting and would be happy to see it discussed elsewhere, but I wouldn't like to see a proliferation of this sort of soft questions, as is unfortunately seen on MO. Many of the latter type of questions are closed there, but much less than should be. I feel that they would fit much better on blogs, for example. At the very least, such a question should always be community wiki, for reasons that have been discussed many times in this (and other) meta.
