Websites Updating!

Okay, so we all love our own websites. YouTube, Facebook, Twitter, whatever. But, some of these websites are always changing! Take YouTube for example. Let's see what it was like in 2006... Yellow Subscribe symbol, easy access to our favorite videos, five star ratings, you name it! Now, let's look at it in 2012... Gray Subscribe symbol, confusing access to our favorite videos, confusing channel formats, and no five stars. I know that other websites are being changed a lot, but this is ridiculous! What happened to the old websites? What are they, dead? YouTube has been replaced, and will be changed again in a couple of years. We all love the old website formats, so what is it that the updaters see?
