@atpfm hello & thanks again from a long-time listener.

In 1990 I began archiving email, calendar, contacts.

Since then I've continuously migrated from every email tool I've used to .PST's, thinking this would be supported forever ... but even msft has now abandoned it.

Ideally I'd fully 'own' my data locally, in some timeless email format usable both by API & UI.

I add to the archive and do rich queries only about twice annually.

Your own archiving practices, and recommendations?

There's a good chance that the ecosystems evolving around ActivityPub, WebFinger, may parallel mail (smtp, pop).

An era of innovation & cooperation.

Then API battles as some scramble for control (vim, mapi).

Then the community digs in to find ways to deal with the problems that come with scale (spam, security).

Settling into the duopoly of A (gmail) vs B (o365), and "other" (fastmail, ...).

The scale phase will be much more difficult in this case, though, but it wouldn't be a bad outcome.
