Kuruma is the place I post longform stuff related to my interests.
I'll admit that Leaflet isn't my favorite. Leaflet is great and all, but I prefer something I can self-host. If you know of software that is both "Atmospheric" (not just supports standard.site but also in that it stores data on-protocol) and has options for self-hosting, let me know. (If anyone that works on Leaflet is reading this, an option to self-host a Leaflet site ala WordPress would count.)
