Delicious
The web's shared memory
Delicious (del.icio.us) invented social bookmarking and popularised tagging, launched by Joshua Schachter in 2003 and bought by Yahoo in 2005. Years of neglect and five ownership changes later, competitor Pinboard bought it in June 2017 and froze it read-only, where it remains.

Ownership [edit]
Why it shut down [edit]
Official line: After passing through five owners, Delicious was bought by rival Pinboard in June 2017 and switched to read-only, ending sixteen years of social bookmarking.
Our analysis: Delicious invented tagging as we know it, then spent a decade being redesigned and resold by owners who each broke a little more of it. Its community had somewhere identical-but-stable to go: Pinboard, whose one-man operation eventually bought the corpse.
History [edit]
Tags, before hashtags
Joshua Schachter's del.icio.us, launched in 2003 with the era's most famous domain hack, let you save bookmarks publicly and label them with freeform tags. That simple act built something bigger: browsing other people's tags became a discovery engine, and "folksonomy", organisation emerging bottom-up from millions of users, became one of Web 2.0's founding ideas. Yahoo bought the site in December 2005.
Inside Yahoo it stagnated; a leaked 2010 slide marked it "sunset", triggering an exodus. The YouTube founders' AVOS bought it in 2011 and redesigned away much of what users loved; Science Inc. took it in 2014; Delicious Media in 2016. Each transition shed users and broke URLs.
Bought by its rival, for beer money
Through all of it, the one-man bookmarking service Pinboard, built openly as "Delicious without the nonsense", collected the refugees. In June 2017 Pinboard's Maciej Cegłowski bought Delicious outright for $35,000, wrote its obituary with visible affection ("bookmarking's most treasured graveyard"), and set the site to read-only. It stands still today, a frozen archive of how the web tagged itself between 2003 and 2017.
