I use jQuery...a lot. It just makes JavaScript development much easier for me. Every so often, I may come across a site where I want to poke around and see what's going on under the hood. In many cases, jQuery is being used so it's simple to spark up Firebug and leverage jQuery to work with a document. While jQuery is very pervasive, there are still plenty of sites that don't use it which forces me to go back to plain 'ole JavaScript. There's nothing wrong with that but I've gotten used to the nice, terse syntax jQuery provides and I'd like to be able to use it.

Awhile back, I came across an awesome bookmarklet created by my jQuery teammate, Karl Swedberg, which allows me to inject the latest version of jQuery right into my page.
