Answer 1

Google Hosted jQuery

• If you care about older browsers, primarily versions of IE prior to IE9, this is the most widely compatible jQuery version

• If you don’t care about oldIE, this one is smaller and faster:

Backup/Fallback Plan!

• Either way, you should use a fallback to local just in case the Google CDN fails (unlikely) or is blocked in a location that your users access your site from (slightly more likely), like Iran or sometimes China.
