Squabbles has an interesting list of media related to it fwiw - like this article mentions: Facebook, Twitter, Instagram, Threads, Reddit, Mastodon, Bluesky, Lemmy, and Squabbles, and the honorable mentions section says how it focused on text-based social networks (nothing about an API) but adds TikTok, LinkedIn, BeReal, and even Pinterest... but still no Kbin (or Tildes, or Discuit, etc.). Nor is it really wrapped up into Lemmy / the Fediverse.
Lemmy describes itself as “a link aggregator for the fediverse,” which to the average person may as well be gibberish. Essentially it’s a community discussion board in the vein of Reddit, based on a free and open platform like Mastodon and Bluesky. You register to a server – or host your own – but can interact with other servers with no issue.
Other articles add mention of like Discord, and even Y Combinator's Hacker News for article aggregation purposes.
Kbin just simply is not considered a major player, it seems. It is not blazing any new trails, nor has celebrity endorsement like Bluesky. At best it seems considered to be "just another instance of Lemmy", and at worst forgotten entirely, whereas at least Beehaw seems to stick in people's minds for some reason.
That said, I have seen one article that mentions Kbin: https://www.maketecheasier.com/best-reddit-alternatives/, which also mentions Beehaw and Tildes and Squabbles, and yet neglects to mention Meta even though the article says that it was posted earlier this month (it also did not mention some other smaller ones such as Discuit). So that is something, at least - as in even if all articles seem biased in various ways, that one at least acknowledges Kbin:-).
