Of course, you haven't done anything wrong by pointing this out. This is basically an issue that really needs to be address. When we come across some certain post, they are three things that determines if we are going to read it or not. One is the topic title, two is the length, and the third is the structure.

In my few years of writing, topic title and structure are what captivate readers. When a topic lacks meaning or is not well structured just like the one you quoted above, then won't attract much interest even when it's short.

I will add further. An important key to writing a good post is simply readability and understanding . If a post can not be read and processed by anyone, then there is no value in it. Which is why, I try to read my own write up, process it and understand before sharing it to the general public. Like you said, the length of a post does not matter, but the ability for readers to grab the key information makes it a quality post.
