> RSS is really simple, so it is still very well supported. Notably, all substack publications automatically have an RSS feed included at https://{{substack-domain}}/feed .
I wonder how long that will last until Substack closes it, I have never seen an RSS feed where the author is able to make it sustainable for them to make money from it.
Substack seems to have done an incredible job allowing people to monetize their blogs. Maybe Substack themselves aren't profitable but the authors certainly seem to be doing well.
As someone who's subscribed to a lot of substacks the thing that brought me there was the availability of asynchronous reading (mail, rss newsletters.) I'm sure I'm not alone in disliking the actual site itself.
