Excellent! Haven't browsed all the links yet, but I didn't see any examples for injecting anything except trackers. Templates for some of the more common scripts like AddThis, and a few advertising examples, would be nice. Not that it's any harder, but some diversity would certainly help your cause.

Let me know if you'd like a few of my more devious snippets to add to your project, like overloading document.write (surprising how many of those damned advertising scripts still use document.write instead of div injection! :-\).

Sorry, didn't mean to imply it was my project. It's just one I'm using for a site with a lot of trackers (some clients do go hog-wild on those).
