Culture and userbase behaviour are just or even more important than the list of features or the UI style when it comes to choose the best place for you on the Fediverse.

Well, I guess that's a factor. I haven't really experienced this, as someone that uses mostly Lemmy and Mastodon. I don't know, I'm speaking from a place of profound ignorance on that front.

You say that some are “gonna get culled” but, with exception of projects that were dropped due to personal issues with the devs, but that all somehow live in the form of forks, the Fediverse is expanding and the diversity of platform types is getting greater each day. In fact, there are categories where more diversity of software is needed.

Yeah I mean, if culture is the breaker then that's that, right? I was thinking pretty exclusively thru the lens of software, and I don't believe that there's enough granularity in use-cases to justify all these options, especially considering they are very much evolving, adding features, improving on several fronts... Intuitively, I think they'd be converging towards a feature niche. The Fediverse is growing, so it grows in every direction and in every way, but, as it matures, I'd expect it to grow narrower. Or... Spikier, since there are several niches... I don't know if spikier gets across what I mean, sorry about that.

If, as you say, there's a cultural aspect to using a certain software-base as opposed to another, then that's a whole other thing. Very interesting... I just hadn't thought of that.
