How are ratings (stars) calculated?
How are the ratings calculated? I used to assume that the number of stars an instructable had was an average of all of the ratings other readers had rated it. But there have been two times that I was the first to rate and rated a terrible 'ible with a half star (one was just worthless and one deserved negative stars for being really bad advice) and it gets posted as "3.68 stars - your rating 0.5 stars". When I rated a new 'ible as a 4, it came up as a 4.
