Google Buzz is really Twitter with a Facebook philosophy. Buzz doesn't really replace Twitter because Twitter is designed to be totally public where someone you have never met and will never meet could read your posts and even subscribe to your stream. Buzz is only to be delivered to people you know. There's no public stream although someone could still read your posts via your profile.

But still, it's hard to discover new people on Buzz. Discovery on Google Buzz is much like Facebook where the system recommends you people they think you should or do know. But unlike Facebook, Buzz is too simple. Twitter simple, where all you get is a stream of consciousness. Facebook does a great job with sections: Photos go here, Videos there, Inbox on the top, etc. Then again like Facebook, comments are threaded and easy to follow unlike Twitter's open RT and @ the world way of dialog.

I'm not sold on Buzz yet, but it may end up being like Google Talk's chat bar in Gmail. I use it simply because it's there in Gmail which is my browser's startpage btw. But with all social networks IMs, it's about where the crowd is at.

Aside: Social Networks/IMs that I've tried and died include:

• Friendster (Friends moved to Facebook)
• Plurk (Twitter was where everyone was)
• Jaiku (Same as above)
• ICQ (Everyone moved to MSN)
• Yahoo Messenger (Same as above)
