Every few years in Las Vegas they blow up a perfectly good casino and they build a new one on the top of it. It doesn't matter if they built it 10 years ago... if Elvis got married there... if its the oldest building left on the strip. There is nothing that will stop the progress (except the economy I guess.)
The internet is the same way. The old is occasionally imploded to make way for the new. Recently I got an email saying that Yahoo was going to close GeoCities. For those of you who don't know, GeoCities was a site where you could build a free webpage. I built a webpage there on July 17, 1997. It is still there, but I gave up on editing it long ago. Sometime in October it will be gone forever. At its peak GeoCities was the 3rd most visited site on the web, full of communities of personal webpages. It could have been the myspace or facebook of the day with the right vision. As it was many people like myself built simple websites and enjoyed their small place on the web.
So the old internet is disapearing.... making way for the new.
