Web 2.0... really?

I was almost surprised when I started reading this article and found out that many of the sites considered to be part of "Web 2.0" are places that I have been regularly visiting or heard about for a long time. Youtube, Wikipedia, Digg, and all the social sites like Myspace and Facebook seem like a normal part of internet that naturally evolved over time; whereas the articles made it sound like these sites were an amazing entrepreneur feat of success that are on the bleeding edge of the internet.

Maybe it is just because I have never been one of those people that "browse" the internet; I usually have a set list of places I go to regularly... so I am not really exposed to the junk of the internet. I am also an avid gamer, which is a community based society as well, so forums and user-based websites are commonplace.

Anyone else feel the same way?
