Archive it or you will miss it

I do something similar; you can see my scripts at https://hackage.haskell.org/package/archiver https://www.gwern.net/Archiving%20URLs

The bigger problem, when personally archiving websites and whatnot, is managing that data, i.e. organizing storage and making it searchable. https://camlistore.org/ seems to be the right software for that, though I haven't tried it yet.
