Did Yahoo kill Delicious? They bought it, didn't do much with it, and sold it to YouTube's founders.

But would it have survived as anything more than a personal bookmark organiser (ie pinboard) anyway?

The killer feature of delicious was popular links, which has since been used as the main structure for forums such as Digg (originally), Reddit, and Hacker News. Curated feeds on Twitter/FB/etc also work to share popular links.

For example, you can use r/longform to find the same kind of links delicious would have provided. https://www.reddit.com/r/longform/top/?t=year.
