Like so many new and shiny things, it was really exciting at first. I could comment back and forth on random trends and topics with my closest friends, without worrying about a crowd of Facebook friends or Twitter followers looking in - people I'd met once, if ever.
But once the excitement wore off, I started to ask myself: what does Buzz really have to add to the already overcrowded social media scene? It feels an awful lot like Gmail Chat, except slower and more cumbersome. It doesn't have the journalistic merits of Twitter (ability to spread news to a large number of followers in a very short time) - at least not yet. And, unlike Facebook, there's little to keep you interested once you're done posting. And then there's the privacy concerns Google has only now started to address.
If I'm overlooking an important redeeming feature here, feel free to point it out to me. For now, I'll stick with Twitter.
