In a thread a while back it was mentioned that you could link to jQuery on Google's server to save your user's some time in downloading the the script (since they most likely already have it in their cache from Google). Some questions arose about versioning.

Google has a full library loader API that you can check out at: http://code.google.com/apis/ajaxlibs/

It lets you include many common and useful frameworks directly from their server, and it has methods for requesting specific versions or just the latest version. If you use any of these I'd suggest using the Google API in the future for the various benefits

At the moment these are what's supported:

jQuery
jQuery UI
Prototype
script.aculo.us
MooTools
Dojo
SWFObjectNew!
Yahoo! User Interface Library (YUI)New!

They also have some other cool APIs like their visualizations one with different charting, graphing, mapping, gauges, etc

This looks pretty interesting.. I might have to try it on my next project. I'm just starting to get into jQuery and I could see myself not being able to live without it before long.

I wonder if you ever have a noticeable wait for Google's servers before your scripts start working, though? That's why I stay away from Google Analytics...
