The frustration for me is then which "flavored" version of markdown you're now using, because the evolution seems to always be "MD is simple and popular" until gets extended with subtle differences. Those subtle semi-random differences in flavors get tiring really fast.

What's the frustration about? Basic things are same everywhere.

If you need complex things, you already have enough skills to figure that out. Also there's almost always a help button around that lists what it supports.

For me the frustration is that you cannot learn markdown once and use it in different places - for non-trivial things you always have to use a reference for a particular flavor.
