April 13th I mentioned an article in Newsweek, the entitled In the New Game of Tag, All of Us Are It by Steven Levy, who talks about the practice of tagging.

Well CNN.com had an article online yesterday,'Tagging' helps unclutter data
Online search categorizes how humans label thing and I thought it was worth a quick read.

Brief excerpt:
"Tagging is fundamentally about tapping the collective human wisdom, rather than relying on a computer algorithm, for search, said Ben Shneiderman, who teaches human-computer interaction at the University of Maryland."

Librarians around the world, like one on the LITA listserv, will note how similar "tagging" is to cataloging. Interestingly the article mentions the problem of controlled vocabulary (or lack of it) tagging will encounter as more and more people start to use it.
