Social bookmarking

In his post on knowledge management and social bookmarks Denham Grey asks “So how exactly are you using social bookmarking?”

We used it at BlogTalk Downunder to track content generated during the conference, a great use. Personally I have not got into using tags to mine knowledge, maybe I should…. The new Technorati Beta allows you to subscribe to an RSS feed based around a tag, maybe this would give me some interesting information.
