Am I correct however that it only works with Hook bookmarks to http/https links, i.e. to webpages?
Is there any way that we could also add hook:// links to Pinboard? I understand those are not websites, but since they work in a browser I wonder if there were a way that Pinboard could activate such links just like they work in any browser.
To my knowledge, Pinboard does not allow app URLs (like OmniFocus:/// , x-devonthink-item:/// , and hook:///). However, we are exploring a solution that would expand the set of information Pinboard could reference. I haven’t checked whether Instapaper and Goodlinks have the same limitation.
