Hyde: It feels just like Google Wave, one of the more disappointing of Google's product launches. It had so much promise and became irrelevant so quickly. I don't want to get duped again, so this has to be a dud.

Jekyll: It's nothing like Wave. One of the biggest problems Wave had was that it wasn't integrated with anything. The whole point of Buzz is the integration -- it appears in Gmail; you can read and respond to updates from any Gmail client; and it integrates a number of social media services.

Hyde: It does nothing for marketers, except to provide more impressions for those sponsored links that run in Gmail.

Jekyll: Wrong again, as marketers participating in social channels such as Twitter, Flickr and YouTube can find their content and messages spreading even further as more people use Buzz.
