Facebook

The Facebook site is a cross between your personal digital scrapbook, and a running discussion with your friends. On Facebook, you can post pretty much anything about yourself, from songs to photos to movies to religious beliefs, and then invite your friends to check it out.

It's also a great way to reconnect with people from your past, including some you might rather had stayed there. In any case, Facebook has undeniably changed the way we interact with one another in the 21st century.
