There's been some amount of whining going on that deserves to be called out. But constructive criticism should always be welcome. Some amount of redundancy, i.e. multiple people complaining about the same things, is unavoidable.

Absolutely. In my experience, there's a really strong tendency from people who are already all-in on fedi to treat "this thing doesn't have feature X that my previous site Y did" as simple whining and respond to it with hostility rather than constructive criticism, you can see that with the thin-skinned reaction to some criticisms of Mastodon back in November about e.g. lack of quote posts or poor discovery features.

They don't treat it as constructive criticism or actual feedback from users but instead as an assault on something they identify with personally, which is a recipe for disaster

I think kbinauts just do things differently than the mastodon crowd as well. It's been just a few days and yet we've already gotten 3 userscripts to modify how kbin works, with some of those features added into the main development roadmap. I can't imagine that happening with mastodon.

Could you, by chance, please give some links to those userscripts?

Unfortunately, it seems kbin search is broken ATM (returns a 500) and google seems to only index magazines, not individual threads, so it's a bit hard to search for them
