Pulling your leg?
You sir are getting BOTH legs pulled. HARD.
I don't like the idea of having to pay more for certain content such as Youtube verses Walmart.com. That is just my wallet's personal opinion.
Arguments for content tiering are from an ISP's point of view: Youtube's streaming video eats bandwidth like a cow eats your lawn. Walmart.com doesn't eat so much bandwidth, especially if your ISP blocks the flash or other bling on the bottom tier. Middle tiers may allow flash or bling on buying sites. That's capitalism for you.
