I’ve added support for Live Bookmarks to my site. I really like this feature on other sites that I read cause it lets you see parts of the sites new content without loading the page. The Bookmark is essentially updated via an RSS feed. I believe Firefox is the only browser to support Live Bookmarks so far. More details are available here.
Update: This site has moved from Mambo -> Joomla -> WordPress but Live Bookmarks are still supported.
