cafe-society.news is always interested in implementing feeds - rss and the nostr global feed so far, but I clicked your link and don't get it.  How about a demo video? 

 nevermind - found the video 

 I think desktop clients are more suited to kickstart this. Maybe @reya and @Magister Michael Dilger M.Sc. can add them to Lume and Gossip. 

 Not necessarily. You could just implement the sharing part, and let people use feeds built elsewhere. No need to build a full editor or anything. 

 I'm interested. But I think I need to do some preliminary work such as the ability to follow hashtags. 

 Coracle still doesn't really have that. Feeds basically supersede that functionality IMO 

 oh... I thought hashtags would be part of it.  Gossip only has person lists so far.

Is there a NIP for how this works? 

 Just started using Coracle after I see your feed. I use it through Safari on my iPhone. I couldn’t make the Extension on my Safari work when I run it through Progressive Web App. It looks a little bit clunky on phone but tomorrow I’ll test with desktop. The feed stuff seems works but It would be great if you add a few feeds under as comments so people can start testing right away. 

 I'm logged into Coracle web. https://coracle.social/notes Where would I go from there to play with custom feeds? 

 Click on the buttons at the top. The three dots allows you to load saved feeds and browse uther peopke's feeds (under manage). The filters button lets you customize feeds.
