A new link organization platform, Kbucket, is now in beta. Kbucket allows researchers and information professionals the ability to categorize, comment, and tag thousands of links and publish the result to a Kbucket page.
Current applications of Kbucket technologies are the Information Professional Kbucket and the 2008 Election Kbucket, with links to the 2008 primary and general election issues.
