I'm a long-time user of free/open source software, and write various things for both fun and profit. I don't take myself all that seriously and I do all of my own stunts.
You can find me at these fine establishments on the web: Open Source Musings, The Monday Kickoff, Weekly Musings. and The Plain Text Project.

Typora's a good editor, but it's not open source as far as I can see.
Why cite it when I can write an article about it ...
Anyway, this article is about dedicated Markdown editors, which Atom isn't.
