Value is subjective.

Some people don't seem to able to grasp this.

A glass of water is more valuable to a person dying in a desert, than it is to someone swimming in a lake.

Just because you spend time on a post, and you think it's good, doesn't mean that everybody else thinks it's good.

A lot of people talk about their "good posts" that never got attention and "bad posts" that got upvoted without deserving it. But you can never objectively state that something is valuable to everybody else.

People can simply have different tastes.
