While looking up importers that I could use to move various third-party archives into something self-hosted, I found an add-on to pull Facebook posts into Keyring Social Importers, an extensible WordPress plugin. At the top of the list of built-in services: Delicious.
"Hey, I used to have a ton of stuff on Del.icio.us! I don’t know what percent of the links still work, but I should at least export it!"
delicious.com is gone, but I remembered they moved back to del.icio.us at some point, so I went there, and found…
Yeah, so I guess that’s not gonna happen. It turns out I exported my bookmarks in 2016 (into one big HTML file), which is probably as current as it needs to be.
The maintenance page mentioned Pinboard, so I looked up some articles. Apparently Pinboard bought Delicious in June 2017 and put it into read-only mode. I know I was able to look up bookmarks on Del.icio.us as recently as January, so it’s at least this July they’re talking about, but I’m guessing the server migration probably failed and it never came back.
The Fanfic Connection
In an interesting twist, I discovered that there’s a fanfic-related history in the past rivalry between Del.icio.us and Pinboard.
TL;DR: Delicious was once extensively used to categorize fic on LiveJournal, but an overhaul left it unsuitable. (Among other things, "/" became an unsearchable character, making it impossible to search for pairings.) There was a mass exodus of fanfic writers and readers, many of whom ended up at Pinboard…and Pinboard’s owner put in extra effort to address their needs.
