I’ve been doing most of my work in the Obsidian Markdown system for a few months now. Gabe Weatherhead has a good guide to getting started with it here, on his Macdrifter blog:
The Obsidian user community is a little cult-like but there’s a good, solid application at the foundation.
The one big addition I’d make to Gabe’s recommended list of plug-ins is the Daily Notes plugin. I use it to keep a daily record of things I’ve gotten done, and daily events.
I’m very glad to see Gabe get back to regular blogging. He’s thorough, he thinks like I do, and he’s not prone to the gushing that’s common in Apple technology reviews.
