Hey 
href doesn't seem to be making it into hyperlinks on new posts. I'm using Safari on Mac OS X El Capitan, if that matters. Here's a test: TEST. In my markdown code that contains a link to my steemit profile, but the link is not working in my markdown preview. I looked at the source, and it's just a bare < a > tag in the html; no href.
But sometimes it actually does work. Is anybody else experiencing this behavior?
