I have a small website that uses jQuery, but I by default point to the Google-hosted version (with a fallback to my own site if that fails), but I also use an older version that's a little over half the size of the current version.

What I'd like to see, however, is a way of trimming down jQuery to only include the functions I actually use. I only use two functions out of the whole library IIRC, so I really don't need to load the whole thing. Maybe one day when I have some spare time and other projects out of the way I'll try stripping those functions out of jQuery and just hosting them locally.
