I’ve been helping Wikimedia Enterprise get familiar with geospatial data this year, including OpenStreetMap. We just released a static dataset on Huggingface & Kaggle joining Wiki* and OSM concepts globally, check it out: enterprise.wikimedia.com/blog/geospat...

New working paper: the Norwegian wealth tax was a huge success. The "exodus" of wealthy people never happened (less than 100 individuals left). Tax revenue increased by 71.5%. No changes in business activity or investment. www.nber.org/papers/w35854
Taxing Entrepreneurial Wealth: Evidence from
Norway, 2021-2025
Marius A. K. Ring
WORKING PAPER 35854|
DOl 10.3386/w35854
ISSUE DATE October 2026
Whether imposing higher taxes on business owners adversely affects business activity by constraining investment and inducing capitalist flight is a central question in the ongoing debate on how to tax the ultra wealthy. To shed new light, I exploit a series of related Norwegian reforms during 2021-2024 that increased dividend tax rates, removed migration-related capital gains tax loopholes, and nearly doubled the effective marginal tax rate on business wealth. These reforms spurred international debate and, allegedly, an "exodus" of Norwegian billionaires (Financial Times,
2023). While I document clear effects on migration, these responses are concentrated among the top 0.1% of the wealth distribution and mostly confined to 2022 and 2023. My results indicate that at most 100 individuals left due to the reforms. I find no evidence of significant outmigration or reduced inflows of startup founders or inventors. I estimate that absent any outmigration, wealth tax revenues would have increased by 75% from 2021 to 2024. Reform-driven outmigration lowers the revenue gain to 71.5%. My findings further show that outmigrating owners' firms remain economically active and do not reduce investment. In a broader set of analyses, I examine whether business outcomes are affected, regardless of whether owners outmigrate, since firms may reduce investment both due to liquidity constraints or distortions to owners' savings decisions. I compare firms owned by Norwegian individuals subject to the wealth tax with firms owned by foreigners and other tax-exempt entities. By merging historical ownership data from Orbis with the Norwegian shareholder register, I perform these analyses on both Norwegian and foreign-domiciled firms.
Across settings, I find no evidence that Norwegian-owned firms pay out more dividends or invest less after the reforms,…

underrated part of El-Sayed’s messaging strategy seems to be shaming journalists who ask dumb questions that play into right-wing frames. you can’t answer these in a way that satisfies them, but you can make it embarrassing enough that you impose a toll on asking.

So many good points in this post by @nsaphra.bsky.social: only quoting a couple, to encourage you to read the others. "My colleagues and students adopt the writing quirks they read throughout the day, and their own writing becomes more like an LLM’s." nsaphra.net/post/uncanny/
To find a nugget of meaning, the user must sift through mounds of slop—and some simply won’t bother. They’ll serve the slop unfiltered to another party, who performs this interpretive labor themselves, only to discover that the underlying meaning does not exist. When someone expects me to perform their share of this interpretive labor, I get angry. Grice’s rules are, in essence, rules of etiquette—their unwarranted violation is rude.

The most terrifying part is the infectious, all encompassing nature of the uncertainty around it. Your awareness rewires, and you no longer perceive like you used to. You can't "unsee" it, even when you aren't sure you're seeing it.

Oof I felt this one. I was not familiar with Paul Grice's cooperative principle, "the speaker is conveying some intent as well as they can". i.e. we used to count on there being some intent behind fluent language. What if we no longer can? Another level of norms collapse beyond social media?

It seems relevant that the thing Isaiah is being sent to do in that passage is to deliver a prophecy of doom to his own people for having fallen away from the path of righteousness. So if these guys were like, Isaiah, that would be robustly bad news for...the United States.

After thinking about this question all weekend, I think my favorite candidate is the alchemical symbol for air: 🜁 It’s connotes both atmosphere and “transfer”. It’s a standard Unicode character. It references a capital “A.” And it’s very simple, which feels appropriate for a protocol, like 🌐 or 🛜.
