He is not on nostr from what I understand. The link we are looking at is LNBeats.com, it is an open source music player pulling rss feeds (in this case instead of podcasts it’s music) and allowing you to listen to them. You can send him a “boostagram” (podcasting 2.0’s terminology for a zap) that will go to his Alby wallet. At the current point, I think the only wallet you can currently bring to boost with is an Alby wallet (you are able to run Alby locally on a node), but I could be wrong.
