I'm one month older and Google launches Buzz. I think this is what many of us have been waiting for. Buzz is integrated directly into Gmail and can import a numerous amount of other life streams.
Buzz is new and will probably take a while to stabilise but already it feels as if it will be adopted very quickly and I presume that it will draw more people to the Gmail platform.
I am glad to see the integration with Google Profiles, this is going to make Profiles more relevant and content rich.
If you're not on Gmail yet the now is the time to open an account. I recommend Gmail to all of my clients as a system to keep track of all of your various mail identities and manage your digital life. Once you've got a Gmail account check out all of the other services offered by Google, most of them are also available directly on your mobile phone which is great.
