I think google buzz looks interesting. Like Ivan noted, the integration between twitter and facebook would be a plus. I don't think too much of google is a bad thing unless its not innovating, and I think the people will be the decider of that; we will either use it or not. For that reason, Google doesn't need a new identity, creating a new one would take millions to promote a new brand and we are already familiar and comfortable with Google.
What do you think about it?

This info is very useful for us.Can you suggest more about google buzz ......?
