For a really excellent, far more comprehensive and much better articulated
series of articles pertaining to ratings/rankings, check out
www.lifewithalacrity.com

Some of the articles include: Using 5 Star Rating Systems, Experimenting with
Ratings, Systems for Collective Choice, Rating Systems, Competitive Ranking
Systems

The ratings users choose are certainly influenced by the presentation of the
rating opportunity. The result of forcing "Come on guys rate everything!" down
users' throats is that if people really dont have an opinion or feel strongly,
most likely they will indicate neutrality. If users have more of a choice
about contributing a rating then only the users who have a strong opinion will
take the time/effort to complete a rating and so you will end up with a
bimodal distribution.

The good/bad or star ratings are always useless to other users without the
accompanying explanation of the review.

_Let users choose from five stars, and they nearly always pick three_

Amazon has the problem of bimodal distributions for their ratings...nearly
every user either votes one star (and bitches, "If I could choose zero, I
would") or five. They've actually started sending emails to people requesting
reviews to fix this problem (to get the silent majority to vote.)

I think the "liked it"/"hated it" options are basically enough all the time,
at least in aggregate. RottenTomatoes.com seems to end up with good ratings
despite reducing the answer space to green or red tomatoes.
