For what you’re doing I think Nostr/Fountain fits because any PC 2.0 people that know you exist are the ones trying out Nostr and will probably respond to you on Nostr/Fountain. That’s how it worked on the last episode you did.
Running Helipad on your own lightning node is the best solution for seeing PC 2.0 Boost and Boostagrams since everything is going to your node. Plus you see the Boosts coming in from other PC 2.0 apps that aren’t Fountain because there is more than just one PC 2.0 app that has lightning.
