This Substack article on NY Times is relevant I think to Stacker News.

The authors are writing for the revenue from subscribers. But Substack is a subscription service, so if they are actually adding social media (e.g., comment replies to posts and podcasts) that doesn't really add to that author's revenue.

Whereas an author who posts on SN gets revenue not just from those upvoting and tipping, but also from the tips on the comments. Sure, SN is starting out with a userbase below where Substack was even many years ago, but the barrier to entry is less on SN. Additionally, relevant, I think -- when a writer on SN gets sats they have access to those sats (and can withdraw their balance) instantly. I might be more willing to reply to comments I see on SN when I can see from previous replies exactly how much was received on which comments, etc. I become better at it because I am economically rewarded when I do a good job at it.

There are a number of other takeaways from the aritcle (and response from Substack) -- worth a read!
