The idea is great, the implementation not so much. Add a simple code block in markdown and the engine gets crazy with quotes getting converted to HTML entities, etc.
Interesting - I can't recreate this. I have a lot of users who use Blank Slate for code blocks so I'd love to fix this, any chance you can send a screenshot? I know I probably got here late but tomasienrbc at gmail if you can spare the time to help me debug.
