recently I've really been enjoying:
Hyperdriven is a really funny story about a group of space-travelers working horrible freelance jobs!
#Wafflefry is about teenagers with social-media based superpowers that they hate.
Radio Silence is about a British rock band on tour and all the social interplay that goes into that.
Jupiter is about a robot scientist who gets mixed up with some bad police.
All of these have fantastic characters and art, and the writing is really fun! I get excited every time they update!!
(Oh, and mine is Crow Summer. It's pretty great, if I say so myself.)
