Google Buzz has debuted with a lot of buzz itself. A few privacy concerns have popped up that Google has addressed here, and here.  Google Buzz has an advantage: A huge head start of users via Gmail. I envision Buzz  being a social aggregator nearing the awesomeness of what Friendfeed was before Facebook acquired them is. Currently it’s no where near real time which they will improve upon. Google has made Buzz a core product integrating it to its mobile site, Reader,  Gmail and even circumventing Latitude for a mobile location service.

It’s young, and has plenty of room to grow. But it’s already ages ahead of where Twitter and Facebook debuted. I think you’ll find yourself using it more and more as time goes on.
