I don't understand why you would remove the hidden data. I understand that size is a concern for somebody who might just be interested in reading a pdf. But this is totally beside the point when studying weird machines. The whole idea is to poke around within the polygot. https://twitter.com/travisgoodspeed/status/92539248920853708...

I mean, the polyglot thing was cool the first time, cool the second time, only slightly less so the third time, and and so on. But by the 16th time, when the PDF size has blown up to 48MB hosted on a slow server, and I’m watching a seemingly-endless spinner as my phone tries to download the whole thing over a poor LTE connection, just so it can throw away all the extra stuff and let me read the few KB worth of text in the issue… as best as I can, at least, when (as with all PDFs) their fixed line width is terribly suited for phone screens, and not all that well suited for any commonly used electronic display…
…well, I start to think that they could do a better job of showing off their savvy and old-school-ness by using a plain old HTML page. Maybe without any CSS - that seems like their style.
