1. These ratings essentially work as a popularity contest. There are different, and possibly better measures (e.g. BLOAT!), but this method is objective at least. (Another objective measure is the total number of links.)
2. The ratings fluctuate to a considerable degree even over a single day. (Particularly lower-ranking weblogs, where just one additional link can move it up ten positions.)
3. The score is calculated as follows: over 400 weblogs are retrieved and scanned for links to other weblogs. A link to a weblog is considered a vote for that weblog; each vote is worth 10 divided by the number of links to other weblogs. (So a weblog linking to 20 other weblogs will contribute 0.5 to the total score of each weblog it links to.)
4. The maximum allowable vote is 1.5. (Otherwise, a weblog that only links to one other weblog would contribute 10 to its score, which would artificially inflate its ranking.) Consequently, if a weblog links to less than seven weblogs, each link contributes 1.5.
5. Multiple links to the same weblog count as a single link. (And you can't vote for your own weblog.)
6. The count is simply the total number of links to that weblog.
7. I've tried pretty hard to correctly count weblogs known by different names. (e.g. with and without the "www.") I don't think I would have miscounted by much, but if your weblog is commonly reached at several different URLs please tell me.
8. Finally, if your weblog is not in my list of weblogs, please tell me.
