Saving, managing, and annotating readings/reference material in HTML (or: will we ever evolve past PDFs?)

Great thread! I must’ve overlooked it because it focused on app-based solutions (Pocket, Reeder, etc.) at first.

This quote of yours nails the problem:

Your rationale for sticking with .webarchive here certainly seems well-founded. I wonder if there’s someone at Apple we can write to ask about the status of the format. The VPs sometimes reply, after all… I’d be happy to send a message and report back if anyone can suggest who the best person to reach out to would be.

Here’s my new question, then. Whether you’re saving things in HTML or webarchive, what do you use to read/markup/annotate them? Outside of preserving semantics and adaptive presentation, have you been able to take advantage of the format further?

I am dreaming of the equivalent of a good PDF reader, but for webarchive/HTML format, with ways of adding richer (e.g., being able to link directly to those comments and highlights) comments and highlights.
