Things are changing now because Substack makes newsletter discovery pretty effortless. After you sign up for one, and then open a different Substack link, your email will already be filled in on the other page's "subscribe" box. So subscribing to that one only takes a click.

A far cry from the old days when the only way to discover a newsletter would be on HN's periodical "favourite newsletter" threads.
