Similarly, if the posting lacks all of the common words that are known about, it would be an indication in the pagerank that it is a tag in bad faith or of a personal vocabulary.

Thanks for your feedback (and the plug for your site – I’ll check it out when I get a chance). I’m sure Google will move this way, but I believe the phrase meant to capture the fact that Google’s search tool is used to retrieve what persons are looking for, not what they are not necessarily looking for. The Long-Tail discussion points to the fact that gems can be found in unlikely places.

I agree with your comment that folksonomies are going to have a very significant impact on the way people store, share, and discovery new information. Plus, tagging is very selfish and still works. Lots of people want to use multiple tags just to make finding and retrieving their information much easier going forward. After all, lots of things are associated with different mental notes (i.e. tags).

Given your interest, I tought you might be interested in checking out our site (www.blinklist.com). Would love to hear from you if you have a chance to check it out.
