De.licio.us is a really cool social bookmarking website. So cool in fact that it’s hot! Yahoo bought de.licio.us last week. I just read an excellent post over at Slacker Manager about how to best use del.icio.us. Now that Yahoo owns del.icio.us, I hope they integrate it with the Yahoo Companion toolbar, a browser add-on that I have used, and depended on, for years.
