For the source code, I wouldn't include the compressed jQuery if possible. Speed isn't as important here as transparency and it's quite difficult to scan to tell whether there are any issues. I know you don't want to take up a lot of room with jQuery but it really will help increase my ability to recommend to others if all the code is easy to read.

You might also want to put comments on slightly scary things like PARTNER_APPS to be sure people don't believe Yelp are YOUR partners or something crazy like that.

Some of these things sound paranoid, but I'd like people to feel 100% comfortable using your bookmarklet.

It worked great for me and identified some things I missed somewhere. Nice work.
