Is social media making our world a small world?

After reading an article about the small world theory from the Washington Post a few days ago, I have been thinking about how many people I have met through social media sites like Plurk and Twitter.  In the two short months that I have been using Plurk, I have almost 30 new friends.  Some friends are as close as a 30 minute drive and there are others who live a couple continents away.  These are people that I do not think I would have met if it was not for social media and the internet.

Do any of you feel that your world has gotten smaller?
