Comments.Lots of funny stuff happens in the comments and most people upvote the most hilarious ones XD
I'm a fan of both, but if I had to choose one, comments for sure. Getting to see what somewhat thought of an update brightens my day every time. Engaging with my readers is honestly just the best part(save for making the comic period). ^_^
I'd love both. Comments would help me engage with the community more as well as help me improve with creative criticisms and encouragement. Likes are nice too, they make me happy knowing someone liked my comic.
I prefer comments, since they allow me to improve and I always like to interact with my readers.
comments! because it's engaging and it can give you direction of what readers want and dont want.
