del.icio.us Adds New Navigation Schemes

del.icio.us has added a number of new features that change how tags can be navigated. You can still view them alphabetically, but you can also sort by frequency. Even better, you can then layer on a "tag cloud" to either sorting. So, for example, you can sort your bookmarks alphabetically, but also view it as a visual metaphor as well - e.g. the larger the tag, the more prevalent it is in your bookmark database. Try it out by clicking on the links below my tags in my bookmark database.
