For me, the biggest obstacles to improving in writing is getting feedback. It's hard because you need to ask people to read what you wrote and feedback is very subjective.
It's really different from software development where you can get immediate feedback without outside help(I am aware code reviews exist).
Feedback is subjective in every field you take. I’ve got a lot of “NITs” in my code reviews, which essentially are - subjective feedback.
I do see where you are coming from regarding getting feedback. I’m pretty sure there are places, like Reddit communities, where you can get feedback about writing.
But I also want to point out an interpreting observation, that I can’t explain. I’ve noticed that the more I write, the better I become at it, regardless of whether I get feedback or not. Future articles are becoming easier to write, sometimes clearer. I also see an improvement in my oral communication. So maybe practice, for the sake of practice - does make perfect.
