Yes, I've been using #coracle feeds + Atomstr as a RSS reader. Ive looked about and there is a bit of a market for rss readers (ever since Google discontinued their Reader), often free for a limited amount of feeds and paying for more features. Seems to make total sense to have a nosyr client with these functions also that can monetise from something along these lines.
Sorta related to algos/feeds, but more of an aside;)
Great point. As nostr long form content becomes more popular (which it will, I guarantee it), we'll see some really interesting long form feeds.
