I know my post does not add value here

And this should be enough.
How to make Hive grow and look attractive for anyone from the outside if people post knowing they do not add anything to it and nobody is interested in the posts? We are all part of Hive - we all should care for it's long term success.
I do not take it personally.

You don't have to be a writer. You play the game every day. Write more about the matches. Why you chose this set of cards and not the other.
Write new text in each post.
There is also option to post different types of posts instead of daily cards reports, or combine both into one. Make it interesting.

Good luck with exams.
