Todd Heistand, who designed this site by the way, has a great list of tools at his site: www.toddhiestand.com. What particularly caught my eye is a wordpress plug-in called “SimpleTags”. I sometimes tire of adding the Technorati Tags, so I may have to waste some time adding them here.
Todd also has the usual list of programs, including Bloglines and Firefox (two programs that I cannot imagine life without), but give his list a look. You may find a gem that has escaped your notice.
