Normally I'm happy to engage in rating submissions. But I'm not going to go first, and I'll tell you why. I participated in a jam recently where there were 3 submissions, including my own. I happily rated the other two, giving them equal ratings. No-one else took part. So what that meant was that I had voted myself into second place behind the other two submissions, which were equal first! I know it shouldn't matter, and it doesn't, really, but for some reason it annoyed me. I felt I'd been duped.
