I couldn't come up with twenty questions for which I care about the answers, not at one time anyway. I certainly would not release them all at once because I could not keep up with all of the responses; or, more likely, it would really be depressing if no one answered any of them. I haven't really thought much about how I approach questions. I just ask them or respond to them.
If I remember correctly, I will usually skim questions that are part of such a blitz, and most of those questions are not that interesting. I have always assumed that was just a part of a marketing effort, or something like that, and moved on.
