Udell reviews Traction (InfoWorld):
There is still no sure-fire recipe for KM (knowledge management) success, but the ingredients must include the staples of the knowledge worker: e-mail, the Web, and Microsoft Office. With Traction Software’s KM solution, content flowing through all these channels is easily captured by the Java-based Traction Server, which can be best described as an enterprise Weblog system. Documents posted to the server are stored as XML, tagged (in a Web interface) with system-and user-defined terms, made available for full-text and structured search, and served back out as team workspaces, enterprise information portals, or both.
Udell has also posted a further update on his blog, also comparing Traction and Radio.
