Re the TLDR: you can tell I have gotten used to a Reddit-style audience indeed:-). But also I enjoy "unpacking" myself here much more:-D. (e.g., can you tell that I also have switched now in this comment to a keyboard? :-P)

You are very welcome and thank you very much for the thanks!:-)

I put that in emphasis b/c I want to keep coming back to it, by adding some new points relating to it:

(4) There really is a "social" side to this place too. That is not a bug but really truly is a feature. We like it even? At least when it is short and easy to pass over - it provides a short-term value, and probably a longer-term one as well, in keeping communities civil & dare I say welcoming?

Sites featuring blogs and articles also exist, if we want to seek those out. The Fediverse would serve as a great way to collect them together, making them more discoverable, but the primary purpose of the Fediverse seems to me to be a "social media" site, so focusing more on the social than on the exact content - and that I seriously doubt will ever change, so any thinking must keep that foremost in mind, the practicality side.

(5) I actually disagree about the mobile issue - or rather I think a much MORE foundational issue is that Reddit was for-profit. That caused them to enshittify their product, regardless of which means you used to consumed it. But then yes, I do see how the device used further compounded that and even here in the Fediverse is going to affect things moving forward, like the overall UI/UX needing to work for both mobile and desktop, putting constraints on what can / will be implemented compared to what would be most optimal for just the latter alone.

(6) Highly relevant to this discussion, it also seems to me that it is a problem of the class of "finding information", such as how you would handle your email. There, putting things in folders has its set of pros and cons - needing effort up-front, especially if a message concerns multiple topics, plus as the set of folders itself grows larger the problem meta-escalates (one email account for home, another for work, each with its own set of folders, so now which account, which folder, in which other sub-folder, is the thing I want? again, especially crossing multiple boundaries like a non-work meeting, but with your work friends, but during non-work time - is that "personal" now or...? in any case it may need to go onto your "personal" calendar if you do not have access to your "work" machine at that time, but anyway the division lines are not always so clear-cut). Conversely, leaving all messages in one huge pile has its pros as well - you'd need to design a "query" to find it later anyway, but how often do you really "search" for emails to begin with, compared to simply read them and move on? - although it is much easier to "miss" messages this way. Which style we use probably says more about our emotional preferences than which is "best":-D.

And relating back to the "social" messages such as emphasized above - those legitimately add information too? They indicate receipt of the message for one, as well as friendliness of the recipient. But is that primarily short-term information, so should those simply be "deleted" after being read, or instead stored along with the rest, especially if they are quick to glance at and pass over while looking for something else? Or should the sender not have even bothered to send them, if they were to be considered a waste of the recipient's time?

Applying the former thought to the Fediverse, how do we "find" the content that we want to see, other than ofc creating it ourselves?

(A) we can create a new sort algorithm, adjusting the "Feed" to suit our preferences, the benefit here is that it affects everyone across the entire Fediverse, who can elect to use the new algorithm or not. But it would take coding, creating consensus, and could take months to more than a year. Google got its whole start as a company this way even, as did the predecessor to Reddit iirc, so the solutions could range from simple to very very complex.

(B) we subscribe to existing magazines, which takes mere seconds and gets us most of the way there insofar as threads at least though not comments.

Oops, it says this is too long.
