Loads jQuery from Google using the exact jQuery version as your current WordPress install while still maintaining backwards comptability for the core
There’s been a whole heap of discussions about the "correct" way to load jQuery onto your site. I thought I’d throw my solution into the ring. What this plugin does differently than others is it loads jQuery from Google - while providing a fallback to the local version in the event the CDN is down or your firewall blocks access to Google. It also uses the same version as WordPress does - automagically.
