I wonder why you have never got any Merit even after writing such big posts.
Oh, yes! It is not about the length, but it is about the point you are conveying through your post, and if what you convey has nothing useful, it is not needed, no matter how long it is.
Learn to be constructive and give out the things that the community needs to know. And then writing articles as big as this one might benefit you as well and earn you a Merit or two.
For sure you are right, but i don't think that this post is big..
It's big enough, IMO.
