> the right approach to this space is building an aggregator and solving discovery/search for all writing on the internet.

This is not the right solution for me. Pocket was the perfect one, even in the first iteration. I don't want discovery. I want a personal box/shelf which keeps a list of what I want to read and what I have read. Permanent copies was a great add-on while it lasted too. Because I want the version I have seen. Not the edited/updated one.

Perch doesn't work the way I want. In fact, it's the direct opposite of what I need.
