Facebook Manners And You

There is no official etiquette book for Web 2.0 technologies, but this comes close. This video, posted on YouTube about Facebook and now re-posted by me on Blogger (Web 2.0 overload!), speaks about the sad state of human relationships that are confined and defined by computers and social technologies. It also illustrates, albeit with humor, the potential dangerous ramifications of positing private (and perhaps false) information about other people.

What are some other rules of Web 2.0 etiquette?
