Just published my first CIP — which stands for "Coracle's Impish Precautions" over on Wikifreedia: https://wikifreedia.xyz/cip-01/97c70a44366a6535c1
If it wasn't clear, this is a NIP for custom feeds.

I think it would be swell if we could achieve interoperability with this. Happy to take feedback for any devs that want to chime in.
In Coracle, you can already create your own feeds, as well as search and view feeds other people have created. Coming soon will be list and feed bookmarking, which will make things even awesomer.
