Pinboard happens to be a web service run along the same principles as the article we're discussing.

The bus factor is high, but I suspect that Maciej has a plan that'll let us download our archive even if he does get grabbed by the mainland Chinese government let alone a forecasted going out of business action.

Pinboard is a profitable online equivalent to a mom and pop shop. It’s sustainable and its founder isn’t chasing growth at all costs. It also has a cult following, so OOB is highly unlikely.

Does pinboard caching work with sites that are behind a login or paywall?

It does not. See FAQ here: https://pinboard.in/upgrade/

This is the advantage to Evernote. Since it’s a browser extension, it has access to anything you have access to.

The downside is, since it’s a browser extension, it has access to anything you have access to.

Agreed that there’s a tradeoff. I don’t think there’s really an alternative solution though.
