What about a "no opinion" button?

To tell the asker, I read the question, and… I got nothing. Because otherwise we’ll just go in and make some inane remark, when maybe the asker was hoping for a serious discussion. I especially want to tell the Jellies I like that I’ve considered their question and have nothing useful to add, but without polluting the answerspace.
(Edit: Crap, just realized, a bunch of smart assess are going to answer “no opinion” variants down there. Sigh. OK, get it out of your system.)
