I'm interested to hear what you think is good/important enough to warrant following, admittedly with the aim of expanding my list. I'd also be interested to hear what reader you use.
Here's my list (most of these are easily searchable so I won't link them):
Cube Drone, Dilbert daily, Garfield daily, Invisible Bread, lolnein, Poorly Drawn Lines, The Oatmeal, xkcd
xkcd what if?, John A De Goes' blog , Still Drinking , Krebs on Security
I use a Telegram bot  as a 'reader' of sorts (no affiliation).
