Recently, I have talked about restructuring the URLs of my website and adding IndieAuth so I could use my domain as my main online identity to login into services. Along those lines, I came across Micropub. In their own words:
The Micropub protocol is used to create, update and delete posts on one’s own domain using third-party clients.
So it’s basically a simple common protocol that could let any website get updated using an arbitrary CMS (Content Management Software) or application that supports it. I really enjoyed the spec and there’s suggestions and issues being worked on.
