Caching is a deal with the devil, in which reliability is traded off for 
performance. For some applications, such as the delivery of static documents and 
images, it can be a pretty good bargain. As you move to the dynamic end of the 
spectrum, it becomes a very bad bargain.

I see JSONRequest as a device for delivering the most dynamic of data. In such 
applications, I see caching diminishing reliability, and with reliability goes 

My intention with JSONRequest is to make it minimal because being minimal will 
make it easier to understand and easier to implement correctly.

It is not my intention to replace anything. All of the existing document 
delivery mechanisms continue to have a mission. JSONRequest's mission is to 
deliver dynamic data. Currently, there is no good mechanism for do that.

Your assumption about Yahoo is at best misinformed.
