"You say you want a revolution.."

"...Well you know, we all want to change the world."

The Beatles knew it in the sixties. They wrote a song about it. Revolution that is.

I happen to be talking about a social networking revolution. Sure, it's a little different that the one Paul, John, Ringo, and George were singing about, but the lyrics still apply.

In the last couple of years social networking sites have really taken off. Boasting over 100 million users, MySpace was one of the first social networking sites to really catch on. Not soon after, Facebook followed. Created by Mark Zuckerberg, a Harvard student, the site first allowed people in ivy league colleges to be 'friends'. The site now allows anyone over the age of 13 to be a user and boasts over 200 million users worldwide. That's a pretty big network.

The newest site to hit the social networking world is Twitter. A micro-blogging site that allows users to follow others and tweet about their lives has quickly become the 3rd biggest social networking site - right behind Facebook and MySpace. The site has attracted users like President Obama, Ellen Degeneres, Oprah, and Larry King.

All of the above social networking sites have changed the world. They have given us the ability to connect to people in other countries and share news and stories with them. Although the population of these sites is huge, it makes the world seem smaller and more connected.
