GitHub Flavored Markdown Online Preview

What exactly does this have to do with GitHub Flavored Markdown? Literally none of GitHub's extensions to Markdown[1] work in this editor...

The source code for the app is using the github-markdown[0] gem to render - so it seems strange that it isn't working.

Edit: Ah, heres the problem: https://github.com/github/markup/issues/47 - the github-markdown gem doesn't support github-flavored markdown, they must use a different gem or branch on the site

Very nice. I really appreciate the dropdown formatting selector box. I use Textile in Basecamp and find myself intermixing/confusing it's formatting with Markdown because the two are CLOSE but not exact.

Thanks!
