There's definitely not enough merit to go around, but every thread I visit is overflowing with padded shitposts in garbage, broken English. Most posts don't deserve merits, period. Just because a post is 500 characters doesn't mean it's not a piece of shit, because there are plenty of them that are far longer--and conversely there are one liners that make me laugh until I'm shooting liquid out through my nose.
OP's English isn't good, so frankly I question his ability to judge a good post unless it's on a local board. I'd challenge him to give some examples of quality unmerited posts.
