No doubt, this is part of the reason this noscript_using_reader stopped visiting TC. Call me a tinfoilhat-guy, but I simply would not consent to the collection of such data. It's ironic that I've learned so much from your analysis of data collection techniques elsewhere.
If the site still functions without these scripts (As it should), then there isn't much of a reason to stop visiting a site because of it.

This sounds extremely useful, would you consider opening the script for public usage?
It measures body focus, number of times unfocused, total focus time, scroll position, scroll rate and a bunch of other things.
It isn't completely working cross-browser yet, but it is close and useful enough where for Safari and Chrome visitors I can see how far down the page they are scrolling and how long the page is in focus for.
