Now, I wish substack had support for math. Adding formulas in images isn't that bad (and practically unavoidable if you want to draw functions - unless you write js), but, still.

Is it a regional restriction?
edit: Thanks to the author for removing the paywall!
Journalists were moaning about 'having to' subscribe to his SubStack. It was actually the first I heard of the place and I thought it was the norm to charge.
It's interesting in that the paywall can be trivially circumvented... by asking a paid subscriber to forward the email of the full post. Costs nothing, but in practice, almost never happens.
Any information people consider important enough to share with the whole world will not be paywalled. Consequently, any paywalled information must not be important.
