So when I log into GMail today, I see information about a new feature called Buzz.
I'll be honest and state up front I haven't done anything with it yet; all I've done is look at it briefly. It purports to automatically tie in to any other Google Apps (Picasa, etc.) that you are using.
In short, it looks like this is supposed to be Google's Facebook/Myspace killer.
Not sure if I really need another social application in my life right now, so I probably won't use it much.
