Why RSS and Folksonomies Are Becoming So Big: "I think the reason Del.icio.us is so successful at bringing the appropriate audience to good material is because they track the changing web by using people to calculate what is essentially ‘page rank.’ They get access to decent fuzzy logic for a fraction of the cost and the democracy of the system allows anyone to get their idea of what deserves face-time into the system almost immediately."
Comment: It's unusual to encounter an article that knocks Google as out of synch with the nature of information online. The author of this post, however, does exactly that, stating that the web is changing too rapidly (Google's page rank system was created when blogs really didn't exist, and the web was mainly about static content)...and that by tracking the nature of the dialogue through tags and RSS, tools like technorati are effective and giving end users what they want, when they want it.
