In my previous article, I introduced some of the exciting new tools people are using to manage information on the Web. One of these is del.icio.us, which is best described as a social bookmark manager. The concept of del.icio.us is simple: every time you come across an interesting site, use a bookmarklet to type in a few keywords about the page, and save it to del.icio.us Web site. All saved bookmarks are public and everything is available through RSS feeds. Like any useful tool, del.icio.us has attracted a number of extensions and improvements as people figure out new ways to use it. Here are a few of those tips, tricks, and tools for del.icio.us that I have found particularly useful.
