Why should you consider using Pinboard?
As a long-time del.icio.us user I was quite surprised when I first heard about the rumors about its shutdown by Yahoo. As I dug further into it I came across their official blog post dated December 17th, and decided to wait sometime before making a move, figuring Yahoo would not simply shutdown the service without ample notice. This comment on Slashdot was eye-opening though, and after perusing some of the alternatives (Diigo, Historious, Pinboard.In) I settled with Pinboard.In and their archiving plan....

The fruit below is called Synsepalum dulcificum, or in common parlance miraculous berry, and was discovered in Africa in 1725, where it was chewed by local tribes before meals.
