Changed the world?

I found this post on Stephen Abram's blog. He has an interesting post regarding 15 websites that have changed the world.

A mighty sweeping statement, what do you think? Agree, disagree or not sure? Have you used many/any of these websites?

I have certainly used some, heard of most of them, but I do not think I agree that all of them are world changing.

But then, that is just my opinion.

ciao for now...
