Regarding point 8, "I wonder if there’s an SEO opportunity here", in which Robert wonders whether Google is giving Buzzed pages an artificial bump: No way, not in the vanilla organic results. You hear these speculations with every new Google service (e.g., Knol), and they're always unfounded. IMHO, Google would be asking for an antitrust case if they started playing that game. However, Buzz results do show up in One Box results, and are prominently featured in the real-time listings, so they are more valuable than one might expect. Also, last time I checked they don't nofollow the links in Buzz posts. ;) So generally, I think Robert is right that there's an "SEO opportunity" with Buzz, but probably not for the reason he thinks.
