I don't know if anything can be done about the way some guys vote up their favorites and vote down their most hateds. True, a fair person rating lots of games should wind up with a bell curve with most of their ratings near the middle, while the up and down voters have upside down bell curves! But they may have valid reasons for voting that way, they rate the games they are passionate about, they don't have time to rate all the "meh" games, etc.

Still, old ratings with no commentaries and no logins in so long? Flush 'em!

With actual commentaries -- email them, warn them if they don't log on... Let everyone know we are looking to freshen up the ratings, perhaps they'd like to revise their older ratings by also comparing them to pins that didn't exist then, and like that.

Since average is actually 7.5ish, just round any rating below 5 up to 5, that'll "normalize" the numbers although I am not a statistician and have no idea if that's what that means.

Finally, add some sort of "confidence factor" where newer games with barely enough ratings to count get a slight hit. 15 votes on one game should not outweigh hundreds on another.

I would lurve to see the resultant ratings.
