I saw some new functionality while posting to del.ico.us this morning. I could choose from my tags below a posting. Nice feature. But this afternoon I again saw a new feature. Steve Rubel had a posting on it. You can now navigate through my tags via my tagcloud. (Update: open the cloud by licking on tags). The larger the font the more articles I have saved in del.icio.us. You can click on a tag to see the articles saved with that tag. You can find the tagcloud also below a taglist or when using related tags.
