@suricrasia these are just the tag search pages, but i imagine some magic could be done to extract the post jsons and make an archive that you can browse to by original paths too. i might take it up at some point, i already run a few other public archive projects so i could probably make this one work too.
and yes, i'd love a css crimes / web art website!
there are sites like codepen which already have the features (including community/sharing features), but idk i don't like the vibe of them, i'd like something that feels like the warm and fuzzy personal web rather than a sleek modern dev platform.
