I haven't used Habla.news or Highlighter, but I have used Yakihonne. I'm hoping for an app that's solely focused on long-form notes, and a larger long-form ecosystem. Something like Substack, but built on Nostr. Where you can subscribe to different authors and pay for those subscriptions using Lightning. I think it could be huge. It could be a great value-add system that drives engagement, and rewards authors for the quality of their work.
