Note that many of the reasons cited in the above links (google CDN is unavailable, user's corporate firewall blocks google CDN ip's, etc.) can be mitigated by using a fallback technique to load jquery locally if the CDN request fails:

Outstanding analysis at the links you shared Jordan!

Thanks for contributing to this discussion.

The idea of having a fall back in case Google CDN is down, blocked, or otherwise didn't even dawn on me as a good thing to do.

I mean Google down? You've got to be kidding but...well...it's apparently happened more often than would be assumed otherwise.

I will definitely incorporate a fall back now.

Great reading.

What Dave Ward says about these matters at some of the links above is quite...well...incredibly thorough. Some of the best, thought out, web development practicality I have ever read.

True nuggets of web wisdom.
