That's an interesting way of looking at it, but you're still talking about "preference" of one over the other. Unless there's a new tool out there that can integrate everything for me, (even if I prefer FB/Buzz/Twitter/etc.) I'll still probably use all of them for those precise separate reasons. I think it'd be interesting to see how many NEW social network users Buzz will bring in, just because of the simple fact that it makes setting up a brand new network easy as pie (vs FB and having to build up to a nice little community of friends).
