Fantastic idea to see what else is out there.
One of the issues I've seen recently with kbin.social website is my subscribed feeds getting drowned out by CATS!!!
Don't get me wrong I love cats but I'm subbbed to about 30 magazine but occasionally kbin decides to fill the entire subscribed feed with posts from m/cats . Hopefully Atremis can be a little bit more broad in terms of which posts from subscribed magazines it presents upfront.
Initially I thought you were saying they subscribed to a single magazine from the same instance three times and was thinking "Is that even possible?".
Then I had a closer look and realised they were 3x different magazines on different instances but all with the same name.
Makes sense that it would appear 3x times.
