I just hate that (1) you can't nest anything into a table (2) it's different everywhere.

Restructured Text is much more capable, and yet here we are, still using Markdown.

My markdown pages often also have HTML in them, I mainly use Markdown so if I decide some overlong thing I wrote on Reddit actually doesn't suck, I can copy-paste it into a webpage, and my web-server's .smd handler does the convertion. Lowest common denominator. :(
