Slate on Net Neutrality

Should the Internet have slow lanes and fast lanes, with companies paying to get on the fast lanes? From Why You Should Care About Network Neutrality by Tim Wu:

In trying to figure out who's right, let's forget about the Internet and look at KFC. The fast-food chain discriminates. It has an exclusive deal with Pepsi, and that seems fine to pretty much everyone. Now, let's think about the nation's highways. How would you feel if I-95 announced an exclusive deal with General Motors to provide a special "rush-hour" lane for GM cars only? That seems intuitively wrong. But what, if anything, is the difference between KFC and I-95? And which is a better model for the Internet?
