A new episode of the Fluidity : "Reasonable Believings"

This episode is more than an hour long.   The epistemological categories—truth, belief, inference—are richer, more complex, diverse, and nebulous than rationalism supposes. metarationality.com/reasonable   You can support the podcast and get episodes a week early, by supporting the Patreon: patreon.com/m/fluidityaudioboo   If you like the show, consider buying me a coffee: h

In this installment of the newsletter for my new event, Fluidity Forum, I wrote an essay about how to design groups.

Three ways for a rich textured social experience to collapse down to a sort of flat samey-ness.

Today Birdsite rolled out a feature in which every user can see how many times every tweet has been viewed. I created and shared a Tampermonkey userscript that hides this.

(Also, it hides the Trending Topics pane. Writing that part of the userscript was the first thing I did when I joined Twitter in 2021.)

My favorite static site generator, Spacebook, wouldn't build any of my websites ever since I got an M1 Mac with the new Apple chip. I did some digging; it took a couple of weeks of occasional work in my free time, but eventually I diagnosed where the problem was. As soon as I fixed it, I issued a pull request with a fix to the project.

I've benefited so much from that software over the years, that it's good to give back and contribute to open source.

You want to know the irony? I stayed away from Twitter from its inception until 2020, when I joined Twitter to engage in conversations with the authors I'm narrating in my audiobook. To my delight, I discovered Twitter's algorithm seems to work well to surround me with what I want.

Twitter is where I go to escape Mastodon.

It's time I admitted this. Hell is half-empty & half the devils are here.

I've run this Mastodon instance since 2019. This server is lovely. Mastodon's Federated timeline has now become what I used to avoid Twitter for.

Ironically, I can't shut it off, because as an admin, stemming the toxic firehose is literally my job.

On the Fluidity Forum Newsletter, I wrote about community formation, & why we have an attendance application process.

I addressed 3 ways for a rich textured social experience to collapse down to a sort of flat samey-ness:

Decoherence: a collapse into, basically, nothing

Vibe Cascade: a collapse into one vibe

Tribalism: a collapse into a mutually-reinforcing conflict process

A new episode of the Fluidity : Overdriving Approximation.

Approximation is a powerful technique, but is not applicable in all rational work, and so is not a good general theory of nebulosity.

Formal methods formally require impossibly precise definitions of terms. How do we use them effectively without that?
