Great change. I would simply exchange the word "quality" for "long form." That's because I consider the example short post you mentioned to be high quality. It is simply not long.

My writing teachers trained me to prize efficiency in getting a point across.

That said, sometimes there is a layering of multiple ideas, building to a complex point. I do think that has more value than any single idea, no matter how that singular idea is expressed. I would hope that such complex content, which is hard to find well done, will get rewarded more. But judging from the content of most media, I doubt it will be.

Time to stop punishing people for being the way people are and work with human nature. People find value in terms of what they are looking for, not what someone says they should want.
