Throughout all this I've written a *lot*--hundreds of thousands of words between r/RoguelikeDev, my older/other blogs, and, most importantly, my current primary #devblog: https://www.gridsagegames.com/blog/
I write mostly about #gamedesign, and sometimes crosspost to other sites, including putting bigger general interest material on Gamasutra where it often made the front page feature (for now they've shut down their submission system since they rebranded the site to GameDeveloper.com :P).
