Only time will tell if it becomes a kind of standard or not, but one analyst I read called it a "game changer": and said that the value of Facebook had dropped by half in a single day. I find it easier to "follow" and "unfollow" people than it is on Facebook, and I am actually meeting new people on Buzz - something that is extremely difficult on Facebook. As for "privacy" everyone seems to have a different definition of that word in the online world, but see more in business most people don't want privacy, they want "promotion" - the polar opposite of privacy. What is it that you want to keep private?
@unoboonex - I think Google wave was something that seemed really cool at first, but on second look not too many people actually wanted to use it. No one wants other people to see them typing in real time - they want the system to wait until their thoughts have been composed and they hit the "return" key. I wouldn't put too much energy into integrating it with Dolphin. I would however, look at the "status" field in D7 and see if that could be some kind of feed that calls Twitter, Buzz, Linkedin Status, etc. I don't think people will want to post that in multiple systems and it would make the profiles in our system always with fresh content. Also, could you bring us up to date on "OpenID" - is that still in the works?
