Easy template injection in JavaScript for userscript authors, plugin devs, and other people who want to fuck with Web page content

The Predator Alert Tool for Twitter is coming along nicely, but it’s frustratingly slow going. It’s extra frustrating for me because ever since telling corporate America and its project managers to go kill themselves, I’ve grown accustomed to an utterly absurd speed of project development. I know I’ve only been writing and rewriting code for just under two weeks (I think—I honestly don’t even know or care what day it is), but still.

I think it also feels extra slow is because I’m learning a lot of new stuff along the way. That in and of itself is great, but I’m notoriously impatient. Which I totally consider a virtue because fuck waiting. Still, all this relearning and slow going has given me the opportunity to refine a few techniques I used in previous Predator Alert Tool scripts.

Here’s one technique I think is especially nifty: template injection.
