I am curious as to why you would use the section "!-- Grab Microsoft's or Google's CDN'd jQuery. fall back to local if necessary --"? Why try and grab it from someone else's site when you have no control over what is there or weather or not it will be available? I see so many people doing this with JS files now. If their servers are down or busy your site just gets slower because it now has to wait for their site to timeout on the request before if fails over to your local copy.
