Echo JS 0.11.0

This is a handy guide but in a world where most production websites still begrudgingly support IE8 and IE9 (and sometimes even IE7), jQuery will remain in my <head/>.

If you use a CDN'd jQuery from Google, most browsers have this cached already so the performance hit of using it becomes negligible, especially since it is being executed on the client.

I'm all for performance, but the DOM remains a verbose, inconsistent API. jQuery is great because, though it might be slower, its API isn't usually ridiculous.
