Why should I use Google's CDN for jQuery?

Question

This may be obvious to some, but I\'ve been wondering: why should I depend on Google\'s server to host jQuery for my site?

Is it only because it loads faster this wa

The greatest benefit is from caching. The theory is that if a visitor visited a site that was loading their JavaScript libraries, say jQuery for example from the Google CDN, then when they visit your website, the library is already in that user’s browser cache and will not have to be downloaded again. This sounds great in theory.

The benefits being shared here and elsewhere are all theoretical. Just came across an in-depth analysis of using a CDN and if it provides the expected performance benefits. http://www.root777.com/appdev/does-using-google-libraries-api-cdn-give-you-performance-benefits
