So why do you hardwrap all your emails by hand to 50 columns? You are wasting my real screen estate. Do you hate me? :(
How can a website not waste horizontal real estate in huge windows without ending up unreadable because of very long lines of text?
This is what your email looks to me btw: https://goo.gl/HLSJ5G

At least you can read the text and see the colours. The Erlang documentation uses iframes and doesn't have navigation links, making it quite useless to screen readers. The colour issues are easily fixable and I think José is happy to get feedback about them. The Erlang documentation accessibility issues are far worse.

Would you prefer 200 characters lines? Because that's not readable by any standard.

It has been years since CSS pixels' stopped corresponding to device pixels though.

Most of the text on that webpage is 12pt. Is the size a problem for you, or just the constract issues you mentioned earlier?

Would tailoring to your specific needs be abuse of mediocrity?

Syntax colouring of examples usually need JS because otherwise the HTML markup to be downloaded becomes really heavy.

Why not? Indices can be long-time-cached JS assets and then searches are very quick and convenient. Cf. searches on https://doc.rust-lang.org/std/vec/struct.Vec.html for example.
