"After my last long post, I got into some frustrating conversations, among them one in which an open-source guy repeatedly scoffed at the idea of being able to learn anything useful from people on other, less ideologically correct networks. Instead of telling him to go fuck himself, I went to talk to about fedi experiences with people on the very impure Bluesky, where I had seen people casually talking about Mastodon being confusing and weird.
"My purpose in gathering this informal, conversational feedback is to bring voices into the “how should Mastodon be” conversation that don’t otherwise get much attention—which I do because I hope it will help designers and developers and community leaders who genuinely want Mastodon to work for more kinds of people refine their understanding of the problem space."
I'd argue that Kbin's a bit more - it's viewing and publishing capacity for users exceeds that of Mastodon or Lemmy given that it bridges the "Redditverse" and "Twitverse" styles of communication exceptionally well. Content is more discoverable as you've got the ability to follow (and block if need be) not only people, but communities and even entire domains, and the search capability scans both Mastodon and Lemmy.
For those using Kbin, your Mastodon posts and traffic show up in the Microblog section.
In my view, Kbin holds the most potential in the Fediverse, both for the average user and the content creator. It's pretty damn cool to be able to view and publish to pretty much every major instance, regardless of the platform they run.
