Meta idea: since people are always making price predictions, I was thinking that it'd be cool to add a "Speculation score" number under your posts/merit/activity while in the speculation section, with the score based on some continuously-running price prediction game. I probably don't have time to develop a game like that, though. But if someone else creates it off-site with the necessary APIs, your site could provide the scores for the forum. Anyone want to create it?
