Though Google released Buzz as a social networking tool, so far it seems to be functioning more as a news feed than an interactive tool. An analysis by PostRank showed that 60% of the content on Buzz is from Twitter. Another 26.47% is from news feeds. That leaves a little more than 10% of the ”buzz” potentially being original content generated by Buzz users.
Of course Buzz is still very much in its infancy, and the powerful potential of its integration with Gmail should not be underestimated. So we’re definitely keeping an eye on it.
