Sure. Part of that is PDF’s restrictiveness. We either value the consistency, value the flexibility or pick the appropriate format for the application. Basic HTML gets you something readable with any HTML renderer, and you can pretty much count on it, but not to the same degree or certainty as you can with a PDF (and bad PDF renderers exist too). You can still read a book in it. HTML+other stuff is where it gets dicey, and temptations like on-demand loading and endless scrolling, or “rich” features like dictionary lookups (that my OS already natively supports in any application from any text selection including the web browser) start to make reading a book this way sound like a bad idea and PDF starts to sound a lot more appealing. All I’m saying is when PDF starts to sound like the wrong choice, consider HTML. Not HTML plus stuff, just HTML. Maybe a very very light touch of CSS if you’re feeling fancy, but it’s really not necessary.
