Why did markdown become popular when we already have html? Because markdown is much easier to write by hand in a simple text editor.
Original SGML was actually closer to markdown. It had various options to shorten and simplify the syntax, making it easy to write and edit by hand, while still having an unambiguous structure.
The verbose and explicit structure of xhtml makes it easier to process by tools, but more tedious for humans.
I'm sure Markdown was already popular, but I agree with the OP that GitHub made it orders of magnitude more popular.
Previously its popularity was somewhat similar to RST.
People had already ditched writing HTML for years before Markdown came out.
People were just using other markup languages like rST.
Other attempts had already proven HTML to be a bad language for rough documentation. Someone then just needed to write a spec that was easy to implement and Markdown was that.
Is it really that much easier to write `<br>` and know that it isn't a problem, than just write `<br />`?
I've been closing my tags for 30 years and I assume that I will for the rest of my days. I like that it validates as XML. Historically I used XSLT a LOT.
Imho the real strength of markdown is it forces people to stick to classes instead of styling. "I want to write in red comic Sans" " I don't care, you can't".
And markdown tables are harder to write than HTML tables. However, they are generally easier to read. Unless multi line cell.
Personally I think Markdown got _really_ popular not because it is easier to write but because it is easier to read.
It’s kind of a huge deal that I can give a Markdown file of plain text content to somebody non-technical and they aren’t overwhelmed by it in raw form.
HTML fails that same test.
