EpicEditor – An embeddable JavaScript Markdown editor.
I love that Markdown has had this sort of resurgence over the past year or so. It makes so much sense to me, and stabilizes so much of the frustration I see clients dealing with when their WYSIWYG editor simply gets in the way. I don’t have much direct experience with explaining Markdown to clients, but a number of them have requested it specifically instead of TinyMCE in WordPress for instance and that’s just awesome to me.
