Important thoughts about URL preservation.

"In our attempts to imbue that nostalgic warmth, we miss the real reason we treasure our old photos: they’re artefacts, hard-copy memories of our lives."

I fucking love this comment from the guy whose tweet kicked off the whole thing (evidently a Y! guy):

"My wedding and baby photosets are on flickr, whereas my last instagram was a sepia-toned perspective shot of a pour-over coffee setup that caught my eye."

Speaking respository of a former flickr engineer, Cal Henderson. Lots of information about PHP and scaling, obviously.
