If you’re in the business of writing plugins for WordPress or are involved at all with the GitHub community, then you’re more than familiar with markdown.
Personally, I’ve tried a number of different markdown editors but have yet to be really satisfied with any of them. For the longest time, I used iA Writer and I still think it’s a terrific application, but I think it’s geared more towards writers and note takers. It doesn’t suite my particular needs.
The majority of the notes that I take are usually in some form of documentation – either it’s related to team meetings, documentation for work I share on GitHub, or README files for themes, plugins, or similar projects.
And as far as those situations are concerned, Mou For Mac is hands down the best markdown editor I’ve used.
