In addition to the warm feeling commenters no doubt get for supporting other writers there's another benefit that comes to the commenter, honest.
A comment on the writing forces the person giving the comment to actually think like a writer. While 'atta boys' and 'way to go' are okay, they don't require any thoughts on the quality of the writing. If, in your considered opinion, the story sucks, just move on. Save 'constructive criticism' for PM's. But taking a minute to mention something you thought was well done is a goodness both for the those getting the comment and for those doing the giving.
Give commenting on stories and poems a try. It won't hurt much, probably.
