It is a fun idea, which has sparked some interest with a lot of people, that is for sure. It could be a running thing where the winner makes the next game (decides on a scoring scheme).
You can also notice that you are least need to post one time to alter your score.
@Ed Collins: (3) The total number of players affect your score. The first result has only 4 players, so the numbers are divided by 4 (I guess), but the second result was divided by 10, and the third by 14, and so on!
Well, my stupid guess had killed it before you posted the last post. I thought PCGSE is clear, but I was totally wrong. Actually I gave up thinking, and waiting for 24th. of June to know the rules :)
@ypercube: It became clear at some point that, as long as you were talking about the game, you could usually at least not *hurt* your score, and usually helped at least a little. At that point, I think people became much more willing to post in the actual game thread. (Just watch out for those consecutive posts!)
