Perhaps you should read the Google "quality rater guidelines". They are from 2007 but the basics will still apply. - [huomah.com...] (moderator note- PDF file)
Interesting tidbits from the guidelines:
~ It's possible to get a Vital rating (the best) and a spam tag at the same time.
~ Google's cache copy may be used to rate your site in some instances.
~ A lot is left to judgment on single pageviews without digging around your site.
~ raters generally come in on your best pages.
Much, much more complete with examples... It sure throws the idea of an algorithm being in complete charge out the window, raters have the final say.
