Google's answer to Facebook finally appeared in the form of Buzz. Not sure how I feel about it but I'll roll with it for a bit.
Some of the doubts expressed by posters in the Metafilter thread centred around not knowing where and to whom updates would go. Like, if you are on Facebook (I'm not) and post something, you know that anyone you have as a contact will see it, and that's it. But with Buzz, it's already tied in to your email and other sites linked through a typical Google Account. So as a test run, I linked my blogger account - I'm pretty sure nobody reads this other than random Couchsurfing people, as I link to it through my info page - wrote this post to see if it shows up. Anyone else catchin my buzz?
