Blue Organizer seems to be a Web 2.0 type thingy that actually works. Worth investigating if you run a blog or use social bookmarks such as del.icio.us. Take a look at:

Ps. it would be neat if I could add items like this via Blue Organizer, but then perhaps I should be using del.icio.us rather than WordPress for this non-blog, blog?!
