1. People do not know its possible

2. It is not designed to work as a single file, and AFAIK there is no universal way to do it.

3. its not as easily editable as Word or Excel to most people.

4. There are alternatives such as PDF.

#1 and #3 are big ones for sure and related. That has to do with most people aren’t developers & don’t code. I get that’s the biggest reason it’s not common. I’m just saying even among developers, I would think it would be a little more common. You can obviously do so much more with it than PDF, it opens a lot of interesting options. I don’t think #2 is a concern at all. The “universal” way to do it is double clicking the file :) every computer in the world will open an HTML document in the default browser (not the case on mobile though).
