Since Yahoo did put delicious into "sunset mode" (marketing speech for: "we will close it down"), I was searching for an alternative. Many people did switch to pinboard.in, so I gave this service a shot. And I am really liking this "antisocial bookmarking service". If you are in search for an alternative to delicious, give pinboard.in a try. It is worth the one time signup fee! The only thing I was missing is a little firefox integration for quick bookmarking within firefox. So I wrote my own little firefox add on. Its called simplepinboardbutton and its hosted on the simplepinboardbutton site.
