@aaronpk Thanks!
Let me see if I understand it. I’ll try putting it into my own words:
Microsub is a spec for a syncing system.
The server crawls feeds, handles feed parsing, and keeps the true copy of the subscriptions list (folders and feeds).
A client app can add/remove folders and feeds and can download the parsed feed data.
(There are additional features, but I think those are the basics. True?)
The two things I think an Evergreen user would still want are: 1) per-article read/unread status syncing, and 2) per-article starred status syncing.
