For my part, I'm delighted to have the opportunity to try and create some distinctive imagery for SI. I've been fortunate enough to have what I think are some good ideas. And now I can be confident that SI will have a logo at least as good as the one I designed! Also, I'm using this as the perfect excuse to finally learn how to use Inkscape; that will be sufficient remuneration for my efforts. (I vaguely agree with the general point about contests tending to devalue labour, though.)
