It’s hard, perhaps impossible, to pick a single favorite from everything i read, but some of my favorites i currently read or have read in the past include Sombulus, Stand Still. Stay Silent., Aurora, Devil’s Candy, Rusty & Co., Tamuran, Vainglorious, and Tales from Alderwood. They’re all long stories, most of which are ongoing, and i have a list of several dozen more with links if anyone wants more. I also enjoy xkcd, SMBC, and Existential Comics.
