What can Web 2.0 Do for you?

It can reduce your cellphone bill for one.
Ever wonder how your plan stacks up against plans offered by your carrier or other carriers?
Well some very clever people have put together a nice service to help you do just that. If you are looking for a new cellphone plan or just wanting to compare how you are doing vs. the competition Bill Shrink can help you do it.
It analyzes the way you use your phone (either by what you tell them, or by importing your bill) and figures out if you could save money by going with another carrier. For the most part it does very good too.
You can set preferences for signal vs cost and filter by plans that will work with your current phone.
All of this is wrapped up in a slick interface. Interested in figuring out what the "Web 2.0" hype is about? Check out this site for a good example.
