I watched the entire 1 hour long Google Buzz Release. Some great questions were asked and what not but what I found most interesting was the fact, that in the video, they had audience members send the speaker messages in reply to a post to show that Buzz feeds LIVE comments to you.
I find it to be a little more than a coincidence that on the Google Buzz website there is a Taco symbol for "Just the Good Stuff". Why do I think that? in that section of the presentation, audience members had a conversation that changed from sushi to Tacos and Burritos very quickly.
Above is a screenshot of the release video, Thank you John Costigan for the Taco symbol!
