Usually I try most new Google services shortly after their release. I did with Google Buzz as well and I didn't like it because it didn't even show up for 24h while the call to action "Try Google Buzz in Gmail" was already in place. Thus I decided to abandon Google Buzz for good like I did with Google Wave. Also I almost never use Google SearchWiki, Google SideWiki and other old and new Google attempts to get into social media.
