Tagging book released
Gene Smith, a consultant specializing in information architecture, just published Tagging: People-Powered Metadata for the Social Web. Although the book appears to focus primarily on how to design a collaborative tagging system online, it may well be of interest if you just want to know more about the current thoughts on tagging as a social phenomenon.
I’ve ordered my copy and will post more about it when it arrives. For more information about the book, check out the Tagging companion website. The book is currently for sale through Amazon.com (I’m not sure whether or not you can find it in brick and mortar stores).
