I don’t miss it because I keep using it. The communities I follow there are niche and they are completely dead on the Fediverse. I keep opening Kbin every other day just to find that my "new" feed still shows posts from 2 weeks ago without even scrolling.
Also, most of what I dislike from Reddit is still here.
Tons of people on the Fediverse craft their responses to fish upvotes, and circlejerking/echo-chambers are here too. Just last week I got a fresh breeze of downvotes and angry commenters because I expressed that I dislike Steam, on the PCgaming magazine, which is the same thing that would’ve happened on r/gaming, r/pcmasterrace or another similar toxic cesspool on Reddit.
Even then, "being the change you want to see" is futile if the platform itself has tons of issues and doesn't provide incentives for people of all kinds to join and use over other platforms.
It seems like only hardcore Redditors and hip techies pass the filter to discover the Fediverse and thrive on it, which makes certain communities outright impossible to grow. Case and point; the biggest solo RPG mag on the Fediverse has been running for over a year, and 98% of the ~40 posts have been made by a single dude, most of which have zero interactions. Why? Because the Fediverse's demographic has no interest on the topic.
And yeah, gaming stuff always make the keyboard wizards rush out of their towers. 🧙♂️
