#2This was a great, easy to read and understand tutorial.

#3This is a great discussion of the mechanics of rendering star ratings in a browser. I'd love to see a companion theory post on how to intelligently compute and rank such ratings. The arithmetic mean is notoriously sensitive to outliers, and the consequences are sometimes severe: I know a resort in Thailand that used to be ranked #1 on TripAdvisor on its island (Koh Phangan), only to fall to #17 after a 1-star review. (The tragedy is that, if you read the review, it's clearly positive—the reviewer evidently thought that 1-star was best. D'oh!) In addition, any sensible ranking should take into account statistical significance, so that (say) a 4.6 ranking consisting of 45 reviews (possibly) gets ranked above a 5-star ranking consisting of one review. How does Airbnb handle these cases, or does it just punt by calculating and sorting the arithmetic mean?

Seems like a site with lots of heavily rated products could do a bit better -- you might be able to use your database of known distributions to inform your prior.

#9It's interesting that the year 2000 way to do stars would be to have a full, empty, and half star GIF, and just to display however many stars you need by doing a loop.
So, when this article says "The goal is to avoid having a sprite that looks like this" where the sprite has all the values of stars in a line... why did people switch to doing it that way in the first place? Like the article says, it's a pain to maintain, has lots of pixels, and is not resizable.

Well, if you do it that way you can change the whole rating by just changing the class name, after you set up all the background-position rules for all the different rating classes. I guess that's why?
