Sticking with my earlier prediction of $1 billion: http://bit.ly/cVcw

As a fan of Robert Scoble, here's what I like: he's always experimenting and pushing the boundaries. That makes him great to follow. And because he has so many following along, the conversations around what he does are equally valuable. People like Seth Godin push the boundaries by the concepts they espouse. Robert does it by his actions and informal comments.

Jeff - I've thought the same thing about media sites using FriendFeed. The experience built there is amazing for interaction and visibility. It seems like a decent revenue model for FriendFeed (in addition to the inevitable ads which will be coming to the site).
