That Schleiss article makes exactly the point I'm trying to make to you. For a publication of your size 375 claps is a dud (that article is using data from when Medium's algorithm's would have been working in your favor). 75% of your articles are completely failing to get traction.
The job your editors should be doing is quality control. They should be filtering what you publish way down. And your job as the publisher should be to set guidelines for quality. None of that is happening and as a result, you're putting a constant stream of low quality in front of people. What's so great about being a top 5K site if you the impact is wasting people's time?
As comparison, I looked at the last 50 articles we published and only found 2 that didn't get 375 claps. Those were duds and we tried to learn lessons from them.
