Shouldn't the quality of the post be what is looked at? I mean, the post can be long or short, it shouldn't matter as long as it is informative. This is just my opinion.
I've been on this forum for a while and although I've not been active and still new, I've read a lot of posts. Some posts need explanation and it has to be long for it to be fully explained.
I agree that there are posts that are just long and full of nothing, but condemning long posts shouldn't be the way to handle it.
I'm still relatively very new here, so I stand to be corrected.
