What about active sub for active sub?
I.e. I suggest to everyone, who are interested in this, to read and comment each other's new issues (well, length of issues of both authors should be comparable), which raises the chances of appearing in "Trending" and "Popular". We shouldn't nesessarily praise each other. I personally don't mind neutral or even negative comments, if they are constructive, honest and aren't offensive. Besides, comments should not necessarily be long.
My story is atypical hard (I hope so) sci-fi with technical descriptions, some brutality and NSFW elements.
I'm already a reader of @OwlComics 's comics.
