Have you seen people post screenshots of text on Twitter, and highlight (by selecting the text) a section they want to call out?
Here's an example:
These aren't "tech" companies. And this isn't a "sharing" economy. It's a profitable route around employment laws. pic.twitter.com/1RrENKT0Y8

I thought maybe one could automate that process, and make it random. It would assume PhantomJS is capable of selecting text as a person could with a mouse (I'm not sure it's possible to automate that part), and then take a 'screen cap' of just the text near and including the selection (I'm sure that's doable). You'd probably want to screencap a "Readability" version of the page, plus it would pick an article at random (somehow?).
