Will all websites be run through Facebook???

The more I think about this "facebook/twitter revolution" the more it's becoming a reality. What urged me to write this post for instance, was a honda commercial I saw a couple of minutes ago, where at the end of the commercial it says "visit us on facebook at facebook.com/honda". I was in shock! No longer is a regular website good enough, now everything is moving to facebook.

From seeing this and noticing the same thing in a couple of other commercials, I thought of this crazy idea... What if facebook just takes over everything, you could access any other website through facebook, including checking your emails, reading the news, etc. etc. all while keep in touch with your friends. That would just be ridiculous, and obviously so absurd that it would never happen... but where will it end? especially if companies are using facebook now instead of giving people their regular website?
