Google Buzz: First Impressions

I've been hearing a lot about Google Buzz lately and lo and behold, it shows up in Gmail this morning. Initially, I ignored it, but I visit my Gmail account quite often and so figured, "what the heck". As I was going through the set up process (which isn't really involved), I was inspired to open up Google Wave for the first time in more than a month. I saw a few new Waves, but nothing like the flood of unread messages I'd expect if I just ignored Gmail for about six weeks. I've written a couple of blogs on Wave, including an an initial review and an update called Why Hasn't Google Wave Gone Viral? My interest in Wave has waxed and waned and now that Google has thrown Buzz into the mix, was I supposed to get excited?
