Pinboard Acquires Delicious — This is the fifth time Delicious has been sold. Founded in 2003, the site received funding from Union Square Ventures in 2005, and sold to Yahoo later that year for somewhere between $15-$30M. In December of 2010, Yahoo announced it was ‘sunsetting’ Delicious, an adventure I wrote about at length. The site was sold to the YouTube founders in 2011. They subsequently sold it to Science, Inc., in 2014. Science sold it to Delicious Media in 2016, and last month Delicious Media sold it to me. Do not attempt to compete with Pinboard.

The article also looks at four novel algorithmic ideas and discusses some emerging areas.
