I go by genre usually. Sometimes I read a certain artist or writer's manga / manhwa, but they usually don't have much out so that doesn't take too much of my time (compared to everything else).

I care waaaaay too much...

mmm....genre for me, because I like to get into the descriptions but there have been multiple occasions where the description was misleading...and I'm reading something....something I really really REALLy don't want to read....and escriptions can be too vague too - like movie trailers :/

I read everything and type reveiws - so i'm not picky

I like excellent art though...feed my EYES...but sucky plot makes everything kinda....mush

Usually it's by the cover only. If it looks interesting, I start it.

i choose by genre to narrow it down and then narrow it down again with the ones with good summary's and reviews then i read a few chapters and if like it i'll read it

Genre then description, or vice versa. But if 'Cover / Artwork' were up there, then that would be first. After that, I'd scroll down to check the ratings, and sometimes the reviews.

i choose like this:

genre -> description -> Cover ->author
