Very cool, thank you.
I think this type of thing is very much needed in the ecosystem. I was looking into doing some sort of content feed/modern rss feed system but had other priorities that came up. High level overview of a subscription protocol proposal
Long term, do you see this as a mix of all notifications like: email, social media notifications, content feed, etc… or just focusing on a few.
Also do you have plans/ideas for extendibility on the protocol? like specifying a certain notification type and data around that specific type?
Just trying to get an idea of the direction
