Thank you for the suggestion, I didn't know about the Brier score. It does indeed look very appropriate for the author page.
If this is a topic you're interested in, I strongly recommend Philip Tetlock's book Superforecasting. The Good Judgment project that he helped launch uses Brier scores to assess forecasters.
Thank you, I've been hearing about that book lately. I'll definitely look into it, it seems very relevant to this.
