With the success of Google+, the company must eventually decide what to do with Buzz and Orkut--either shut them down and port their users, or risk creating a fragmented social ecosystem.
As part of the proposed FTC settlement, Google is barred from "future privacy misrepresentations," and is required to participate in a comprehensive privacy program that includes 20 years of audits.
Google Buzz has been surprisingly slow (meaning, it's taken a couple weeks) to reach mobile users, but now it's finally integrated with Mobile Gmail so every smartphone user can buzz their lives away.
You follow the same person or company on Twitter, Facebook, and Google Buzz, and every other time you see an update you get déjà vu. You think, "I've seen this before..."--and you have, because they're automatically posting the same content across different social media networks. Piping feeds from one network to another is a zero-effort way to broadcast content, but it also offers minimal returns.
