The /popular/tag algorithm is busted now, and regularly coughs up very obvious stuff (python.org for tag python, iirc.)

Agreed. I enjoyed that delicious.com was a place I could find articles related to a subject, not the site itself (if that makes sense).
delicious.com is not a stitch of what it was.
Yeah, it doesn't seem to support tag unions anymore. I know it didn't for a long time when you were running it too, but then when it did, it was an awesome way to find things based on topic.
