@rauschma there are two minor changes to the spec which can make the feed content-addressable and reduce duplications (when we have the same article from different feeds): 1. author public key and digital signature, 2. trusted timestamps https://en.wikipedia.org/wiki/Trusted_timestamping
I can’t overstate how pleasant it is to consume various kinds of content via feeds. For example, you can group it into categories, which makes it easy to skip things you’re not interested in at the moment.
Thanks to JSON Feed (*) it is now easier than ever to add feeds to websites. I could even see myself subscribing to a feed instead of an email newsletter to be notified of an important event (such as a product coming out).
