holy crap. Second impression: I'm hooked. This application is so sticky. I am now following only a few people, but occasionally seeing their links on the bottom of my browser is becoming very interesting/addicting. I am also browsing through some of my old bookmarks and sharing them. IMHO, I'm finding this application to be much more compelling than Twitter.
