The pricing page is a good example of what not to do. If you're going to list distinguishing features/limits for various plans, please don't put "unlimited" on the free plan, limits on other plans, and force everyone to dig through your terms of service just to understand the real limits.
Also, a plan that automatically "upgrades" based on criteria tucked away in the ToS should probably just be called a trial, and the conditions that cause that trial to be converted to a paid plan should be explained somewhere on the pricing page.
