I want to post a separate response to this. Yes, the lack of that changes how people participag on SO. I think it's a considerable reason why SO is the large resource that it is, with as many answers as it has. If askers could delete their questions (and thereby had the ability to make my answers un-google-able), I'm not sure I'd bother to answer, for example. Would you?
