I'm no big fan of Digg either. I do like del.icio.us, which as you know allows you to network together with like minds. I also like stumbledupon which is a very interesting way of finding new stuff. Unlike diggers, stumblers are not abusive at all. Stumbledupon can send 20,000 + people your way, however they do not hang around very long and rarely interact with the site as far as I can tell.
