Just a general question. Google hosts several libraries such as jquery etc (http://code.google.com/apis/libraries/devguide.html) and the google fonts library. I have read that a benefit of this approach is that the library may be cached in the browser from a previous site. Webvanta also hosts some libraries or I can upload them on my site, I assume Webvanta has a form of internal caching since the site loads pretty fast so I figure that using a Webvanta or else a local library would give me the best performance.
Has anyone tested this or have any thoughts?
Same with Analytics. I removed google after Webvanta started theirs. Is there a reason to have both - Does Google give me an SEO cookie for using theirs? Do they provide different information?
