I wrote a simple jsfiddle page that show you the current stories in /r/all and their associated ratings as calculated by the hot algorithm:

One thing I noticed is that the stories aren't sorted by the algorithmic score in strict descending order. I recall some mentioned that reddit mangles the ups/downs score exposed via their API. Is this the reason?
