I get that a question brings more engagement, but if I don’t have a question, I don’t have a question. And I might have a thought I want to put down in writing, and maybe someone will read it. Even if no one happens to read it, putting it where someone could read it and not just on paper or a nowhere unknown blog can feel better.
Healthier, maybe less combative from getting a better understanding of who someone is.
Start a blog is a little like “If you don’t like the huge corporation, you have to start your own huge corporation to crush them”. Make a blog, never be seen again.
As for people giving their thoughts, it seems held back until you free it with a link or a question.
