Is the world ready for Google Buzz ?

Google launched their new social networking tool Buzz on February 9Th through their Gmail feature as an answer to the popularity of sites like Twitter. Now when a member logs into their Gmail account, they can chat with other members on their email list.
By incorporating Buzz into Gmail, they are allowing users to be connected easier,but it is this simplicity that may be turning off users. By including members already on your Email list, Google is assuming that you want to be connected to these individuals. It is because Emailing is the most popular form of communicating on the web that people what some type of separation. With a site like Twitter, members seek out people to follow and people who will be their followers. Google has assumed that everyone on my Gmail list are people I actually want to be connected with,but in fact many people on my list are those connected through work or business and don't need to know my every action. And what about those people who are not on my Gmail list? the popularity of a site like Twitter stems from the fact that everyday people can follow celebrities, but not be intrusive. Will these same celebrities be willing to give me their Emails so we can "Buzz" each other? I think this may be too intrusive.
So while Buzz may be convenient for some of my relationships, it is still too early to tell if I can build up the same type of following as I can on a site like Twitter. Google's efforts to keep members on site longer through Gmail, Google Wave and now Buzz remains to be seen if they are biting off more than they can chew.....
