Yeah, Yahoo is now waffling that they're going to sell it, but if so, they compromised its value in a big way by firing all its staff earlier this week. I'm betting it's sunk.
Possible new homes:
Pinboard: simple, has revenue model, api
Diigo: does more than bookmarks, in-flux api
Google Bookmarks: simple, unlikely to go away, no api
The decision was easy for me. Simple beats bloated. Last night I migrated

I'll probably just retire the delicious account for my fic links. I like my archive site better.
The real loss is the single-site searchable bookmark archive that Delicious had become for fandom. LJ is a horrible home for fanfiction because it's not searchable or indexable and a million other faults, but Delicious was a nice workaround. Now all that data is there in one place that's going away. Will fandom migrate its data? Will that data all end up in the same place? I bet not. That's a loss.
Sometimes software moves forward instead of backward department: I approve of the new AO3 "like" button, though I have no idea why they had to go all twee and call it a "kudos" button instead of the like button it so very obviously is. When there is already a word in screamingly common usage for an interface concept, you use that word for your implementation of it. Using anything else weakens your user experience.
