The quality of your writing has not gone down. Sorry you're not benefitting from the uptick that some people have seen. It seems completely random to me. I said the one about accidentally killing your friend should have been boosted. I feel the boosting thing is very biased towards people who've got an editor who likes their work - which is great for them, but hardly representative of us all, or fair, because the people who recommend these stories for boosting cannot possibly read everything.
