This is my first time reading about Edsu, it seems very similar to the Solid Platform in one important aspect: it keeps data in the control of the user, separate from applications.<p>I like how low-level and simplified the protocol is, being limited to only 9 types of messages. Compared to Solid which carries baggage from RDF, this seems far easier for third parties to implement.<p>The note-taking app is really under-selling the protocol beneath it. What could help sell it better is by doing something better than a centralized platform can.
