Thanks for the pointer towards digg. I'd glanced at it a couple of times in the past, but dismissed it as a del.icio.us clone. You're right, it isn't (sorta). I always thought that del.icio.us didn't have enough "social" in their "social bookmarks" and it looks like digg adds what I felt was missing (though the user base feels a little farkish to me, I might just be getting old :).
