Apply HN: Pinboard – Make Y Combinator Great Again
i have a different take on this . I think buffer and pocket have done great work in this year. Obviously pinboard as well. 
I am not sure if I am the only one but I think the problem is bookmarking. On HCI terms, bookmarking is not intuitive to how human brains work. Instead we just go through events and the nature of events makes us AUTOMAGICALLY index them in our brain and when we wish to retrieve them our brain just uses that index.On those lines I think it should be more like log everything that I hit on all my devices and make the search organized. Something similar using apriori algorithm was my school project and I used it a lot until now when I have slowly moved to pocket.My 2 cents - "In short better to have a smart search and indexing instead of bookmarking "
