Google Buzz in Use

I am now signed into Google Buzz and understand generally how it works. I have also attached this blog to Buzz to see how that works. It also integrates location knowledge. Join up and follow if you would like to join in my experiment. Note that you have to have a Gmail account to be there. That is the big barrier that I see to it being competitive with other social networking approaches. If you are already there it can be used to publicize your blogging and thoughts to other GMail users. Update: More insightful criticism.
