Matt Reich, writing for us over at The Sweet Setup:
There’s no shortage of Markdown editors to choose from, and many of them are fantastic. We think Byword is the best of the bunch because it hits the sweet spot between simplicity and functionality. Byword offers a calm writing environment, yet has just enough features under the hood enough to make you a happy and more productive writer.
Byword really is a wonderful app. I do all my long-form writing in it, which includes all the articles I write here and for other sites as well as the book I’m working on right now.
