First, actually reading before speaking? And going to the trouble of citing your references?! This is absolutely an example of what I was talking about in terms of holding ourselves to higher standards. I get it - it is outright fun to share memes and short quick snippets, and there is room and value for doing that too, in line with the context that is offered (some posts call for more serious discussions, memes call for just fun, but oftentimes an article/thread can have responses of both types), and I do that myself too even, but there should also be room for deeper thoughts as well? Which by their nature tend to be downvoted or at least ignored, b/c people are not always in the mood for a wall of text, even if thoughtfully and lovingly crafted.
One example could be to add to the upvote system (or on kbin there is a "boost" that is the true upvote, actual upvotes are not counted even though they are displayed - yes it is complicated!:-D) a new thing like "favorited" or "loved". Yes, people would game that too, but maybe if you could only use one of those a day, or ten per month or some such, then people would have an incentive to hold those in reserve (people could still game it with alts, so like anything else, it may need some attention, but perhaps that is not enough of a criticism to simply not move forward and start doing it?). Netflix similarly now has "up=like", "down=did not like", but also "double up=LOVE". Implementing that across the Fediverse could allow distinctions between content that you merely agreed with, vs. content that needs special distinction as being LOVED. Even Reddit allowed awards, to meet that same need. Btw, I nominated your comment in the m/BestOf magazine for a vaguely similar effect, except that magazine has extremely little traffic (I am not even subscribed to it myself, although in my defense I do keep trying but it always goes to a new page displaying the single word "Error" whenever I try), and also it is far too much effort to do for every post that is worthy of such distinction.
I almost hesitated to respond with these thoughts, b/c who am I to suggest something that I am not willing to implement into actual code? That said, my responding to your existing comment seems a different matter, since you do seem interested in this topic, rather than an entire post requesting/demanding that something be done.
I wrote out a somewhat long-winded I suppose explanation of my personal experiences that led me to believe what I do, but I exceeded the character limit so I will have to post it separately, at which point you can peruse it at your leisure or just skip it if you'd rather.
More importantly though, if you are interested, here is an - I think - extremely insightful article about the short-term blurting types of comments, which again I do myself, we all do, acting to drown out serious discussions: https://kbin.social/m/BestOf/t/113715/The-Ennui-Engine-or-how-chasing-short-term-gratification-drains-our. I am not sure that I hold out any hope for change, but at least I enjoy trying to educate myself on such things for the sake of my own sanity:-).
