I imported my pinboard to raindrop.io and made the recs part of it public here: https://raindrop.io/victoriap715/recs-and-links-28986963

I don't believe it has the network aspect that pinboard and delicious had, but before yesterday I thought it was all public with no option for private bookmarks, and learned that it is the opposite - everything is private unless you make it public by creating a sharing link. The tagging and bundling functionality is great - it's the networking aspect that we stand to lose, I think.
