I still use bookmarks (Pinboard) but I like your approach. I'm slowly trying to remove all reliances on third-parties as I can as they're too ephermal. I'm guessing you went with print to PDF because saving the page from the browser would result in broken pages? Have you found that the PDFs don't look very good for some websites?

Alternatively, you could use a tool or extension that does full-page screenshots and then run image optimisation on them. I do this a lot for local Pinterest-type inspiration store. At the moment I use [Nimbus](https://chrome.google.com/webstore/detail/nimbus-screenshot-...) but it seems like evert few months the extension I'm using starts to fail with certain websites (scrolljackers, mostly), and I switch to a different, newer extension.

Alternatively again, but back to saving websites, surely someone's created a nice tool that will download a page to store it as an archive that won't be broken? Pinboard for example has archiving for an extra fee, so I wonder how he does it at his scale.

Related to your problem grep'ing, I'm slowly working on a small idea to have a local tagging/metadata approach for finding things.
