You know all these Social Bookmark managers that are just too cool? Well, Gordon Luk’s has been working on his own tagging system called, Freetag. It is very interesting to see how these systems work and looks like a fun project to pickup on.

Freetag is an easy tagging and folksonomy-enabled plugin for use with MySQL-PHP applications. It allows you to create tags on existing database schemas, and access and manage your tags through a robust API.

Also note that Freetag is an Open Source Project. Great job Gordon!
