a few weeks ago I decided I wanted to be in charge of my own bookmarking infrastructure, so I exported my bookmarks from pinboard and spent the afternoon writing ~500 lines of python/html/css/bash to make a lil bespoke database manager/static site generator. pleased with the results: https://bookmarks.decontextualize.com/ (there's no link to the feed on the page, but it does support RSS! check the metadata)
