Markdown is cooler than traditional WYSIWYG, but the editor could benefit from having familiar controls
I will admit that I do love the fact that this forum software uses Markdown. It's clean, easy to learn, and easy to read in either text or formatted view. It certainly is not "old school"; I've seen WYSIWYG editors since the 90's, markdown was invented around 2004, and only recently began gaining in popularity (thanks to GitHub and Stack Overflow). I like to think that traditional WYSIWYG is to Markdown as MySpace is to Facebook.
But to be fair, it seems it's really embraced by people in the tech industry, but that's because we're familiar with the alternative of editing raw HTML, which is what is output by WYSIWYG editors anyway. There are many reasons why editing and storing HTML is bad / cumbersome, but the layperson is unaware of it because it's been hidden behind the WYSIWYG editors.
What seems to really bridge the gap is SO's editor, which would be more familiar to most people (because of the many options), but it still outputs and allows input of Markdown.
But that being said, I respect you guys @julianlam @baris @psychobunny for not catering to every request. You have a clear vision of what you want this to be.
