It is indeed! You reminded me of a podcast that I listened to, sometime back. It said something very similar, that the writer is responsible of presenting the idea. But, not how each one of the audience perceive it.
It's probably happens to you more often, as you write more on a weekly basis.
It is hard for me to figure out since I rarely receive comments, but I notice it if that is the case. I am totally fine with it. It isn't different how we look at paintings, sculptures. It is all art. Even comics, memes and emoticons we all interpret in a different way.
I agree, it is all a form of art. Even if not every post is commented on. But, there's a good chance of someone misinterpreting your text or, having a totally different view than what you tried to explain. Especially that, we have a combination of people from different backgrounds with different native language.
