I’ve gone to Gmail 5+ times today to check Buzz. So yeah, I think this is going to be a social network *I* use a bunch, now I guess we just wait and see what happens long-term. But when it comes down to it, and everyone has smartphones, suddenly the fact that most of my friends are already on Buzz and I can see their locations makes it far, far more useful than other location-based services.

Ultimately, I don’t think anyone’s going the be the Microsoft Office of the space. For almost everything, we all use more than one service/device, and I think Buzz just launched into being a major player in it’s space.
I’m going to gather my thoughts on this though, and write a proper article on this in a week. Having just launched less than 48 hours ago, almost any analysis on the platform is a little too knee-jerk for true perspective. I know a week isn’t a long time, but it’s enough for me to have a slightly better idea of the big picture.
