As a programmer, being able to have something like what GitHub does (Markdown text, you can preview what the rendered version looks like) would be great. I assume that people who are less technical would like a more WYSIWYG editor but as long as the ability to write straight Markdown is there I am sure that I wouldn’t care. Oh, and make sure it’s actually a reasonable subset of Markdown, not like Discord or Slack where you support bold and italics but mot much else.
