What’s your issue there?
Plus I can't use web tools, like "Read this page" in Mobile Safari.
And copying and pasting is harder.
And I can't link to individual sections.
I'm honestly baffled by people who prefer PDFs for this kind of information. Are they printing them out on paper and going at them with a highlighter or something?
I don't know that I'd go so far as to say I 'prefer' this, but there are a lot of PDFs out there, this works fine, and it's a nice change of pace given how much time I spend in front of a monitor / laptop screen.
