Google Buzz explained

Courtesy of Lifehacker, here's an in-depth article with videos on what Google Buzz is about.

Buzz's five key features, as laid out in the event at Google HQ today, include:

* Automatic friends lists (friends are added automatically who you have emailed on Gmail)
* "Rich fast sharing" combines sources like Picasa and Twitter into a single feed, and it includes full-sized photo browsing
* Public and private sharing (swap between family and friends)
* Inbox integration (instead of emailing you with updates, like Facebook might, Buzz features emails that update dynamically with all Buzz thread content)
* "Recommended Buzz" puts friend-of-friend content into your stream, even if you're not acquainted. Recommendations learn over time with your feedback.
