Facebook is really insane. I've had several "holy shit" moments with people from the distant past contacting me. Some with new last names, surrounded by young children, some successful, others less so.
Facebook is simple technology that could have existed 10 years ago. The most important feature isn't the tecnology at all - it's the massive user base which was made possible by the popularity of the internet. The utility of the application is increased by the number of users who contribute content to the site. Web 2.0 is so different from the early years - it's still all about content and experience, but user contribution now largely defines the content and experience. That simply wasn't possible with newspapers, radio, or television and that's pretty damned cool.
