Actually, the verdict is still out. The problem I see with Google Buzz is that it is open only to Gmail users, which isn’t exactly open. After all, not everyone has a Gmail account and not everyone wants one. But for those who do have one and use it often, Google Buzz may actually be a worthwhile social tool. But what if you have friends who are not Gmail users? Then, I guess, you’ll have to connect with them somewhere else.
To me, that doesn’t exactly spell success. If Google Buzz does end up being a successful social network it will be despite is flaws, privacy concerns included. But I wonder just how many people will actually use it? And will anyone prefer it to Twitter or Facebook?
