alt Hacker NewsBS is slowly but steadily growing their userbase. Knowhing how did it go for their other purchases, of which I was using many (Komoot, Eventbrite, Meetup), not a single one has avoided constant nags of prompting for upgrades and dark patterns, so this will most likely end up in a similar way.
As many share, I used Miro and found it quite nice.
Komoot is particularly bad, I paid for a lifetime license but now they are gating new features behind a subscription. I think it's time to find something else.
