A lot of excellent texts I've come upon are not immediately capturing one's attention. In fact their intro text could be utterly lame and/or boring.
I do read, top to bottom, a lot.
And the scrolling js thing might tell even more than if they "scrolled to the bottom of the page", if it incorporated time data, i.e how much time it took them for each scrolling. If it took them long enough to scroll, then we can bet they actually read it.
Or, even better, use a Linode image with WP already installed, boot it and you're in business.
Tor might have fixed the block, but an Iranian using the system could still be imprisoned by the government for using it...
Something that, magically, Manhattan, say, has managed to avoid.
Oh, and your experience is "borrowing an iPad for a week".
Er, try Automator.app for an example of non text-stream "composability". Also: Quartz composer. Also: Max/MSP.
Oh, and text-stream composability might be the "unix way" in, but is not exactly programming, it is command line glue.
Composability in programming itself is achieved via other means, for example objects, widgets, components, messages, etc.
