At the annual PCForum conference this week, one of the recurring discussion topics was "tags." This new meme refers not to graffiti, but rather the identifiers that some applications (like the photo sharing site Flickr, which Yahoo just bought, the public bookmark aggregator Del.icio.us, and the weblog search tool Technorati), allow users to create. The benefit to tags is that they let groups of users create ad-hoc taxonomies (currently being dubbed "folksonomies") which can be used as way to slice any large data set. For example, to quickly find pictures from PC Forum, just look for the photos on Flickr tagged with "PCForum."
Tagging will become a highly useful tool for teams, since it will enable them to quickly clump together work-related data. Watch this concept. Also, see more from Release 1.0.
