It's not fair to call it "Blueskyism" because it really started on Twitter and Tumblr and was prevalent on Mastodon until many of those people moved to Bluesky between Nov 2024-Jan 2025.
I had to create a long list of block rules (like I don't care if you car blew its "transmission" or if you came from "transnistria") [1] to be able to stand Mastodon, I even blocked sci-fi writer Charlie Stross [2] because he kept saying mainstream politicians who hear "the call of the mild" like Keir Starmer were fascist. My impression is that Mastodon is getting better lately, I dunno if the obnoxious people are in despair, moved to Bluesky, came to the conclusion that it was their fault Harris lost, or if I finally blocked the last one, or if my tribe found me or if I just don't care anymore.
I share 5 photos a day and about the same number of articles similar to what I post to HN on both Mastodon and Bluesky. My feed is full of other people's photos and similar sorts of articles. I use the tools available to suppress angry people and it works -- I get mostly good engagement, maybe one hysterical angry person a month. I'm not there to pick fights the way the people who Neil lionizes do. It's their business, it's how they drive traffic to their blogs.
Where I do see the negative people is when I play the followback game where I pay attention to two variables (but don't take rigorous notes) One of them is negativity, if their bio says "#BlueCrew", anything about politics or that somebody is "diss abled" or blames their problems on somebody else I won't follow them. In sets that I look at it is typical to have somewhere between 20-60% negative people. I am noticing really poor follow-back performance from the academic science sorts of people and first thought these people were just stuck up but then noticed a lot of them posted last 1-2 months ago. So it could be they are getting too much bad engagement or not enough good engagement, it fits with the story of decline that we keep hearing about though.
I keep thinking about automating my followback spamming and that would require developing a classifier for negative people and if I did that I'd be getting good stats but between taking photos, developing photos and posting photos and Arknights I haven't gotten around to it.
[1] I don't care if it's a good thing or a bad thing, it's that people are angry about whether they are for or against it and anger is contagious.
[2] If only he kept writing books like Iron Sunrise and Singularity Sky but he broke bad the way Niven and Heinlein did in the 1970s.
