With the popularity of Markdown, and notably some great apps in the Apple ecosystem that feature the syntax, I always wondered if Markdown’s creator used any of them.
Some people find this surprising, but I personally don’t want to use a Markdown notes app. I created Markdown two decades ago and have used it ever since for one thing and one thing only: writing for the web at Daring Fireball.
Gruber likes Notes for what I’ll assume most people use Markdown apps for: taking notes. Smart Script won me back over to Notes, but it really is a great WYSIWYG editor.
