O'Reilly Radar Launches

O'Reilly Media has just launched a great new blog called O'Reilly Radar, where the popular publisher covers the latest trends that inform the publications and conferences that O'Reilly is known for.

There's a lot of cool new features that have been built into the Movable Type-powered site. As the credits page shows, Professional Network member Tim Appnel helped create a slick folksonomy system for the new site, taking the popular technique of using tags to label content and building some clever extensions on top of it:

One of the interesting aspects of our work on the Radar project was developing the necessary infrastructure for implementing a content folksonomy in MT. In addition to the tagging and indexing of content similar to del.icio.us bookmarks, we developed a means of producing tag visualization layouts in MT's templates. Like Flickr tag size indicates its volume, but we also added a gradient feature to indicate what Rael called its "entropy" -- a measure of its most recent use.

Congratulations to the entire team on the launch, and we'll be watching the Radar with interest to see what's coming up.
