Not the parent, but ClickSpring is one of my favorites, though they don’t post much anymore. Also, ThisOldTony. BenEater, TechnologyConnections, Jeff Geerling, GreatScott!, Wintergatan, bigclivedotcom, JK Brickworks, The 8-Bit Guy, and Usagi Electric are more on the tech side of my subscriptions.
It would be great if there was an easier way to share subscriptions.
