Three sets of walls are being built on the internet:

1. National Firewalls (Ex. China, Australia). Block sites at ISPs.
2. Walled gardens, ex. Facebook; iPhone Apps.
3. Traffic tolling at ISPs & end users. Express lanes and clogged lanes. Pay to play. There will be nose bleed seats and front row. Which are you going to pay for?

Enjoy the amazing freedom and creativity before it is totally gone. It will be gone that much is certain.
