Dornfest wrote on his own company blog today that he’s closing Values of n, and turning off its two services—Stikkit and I Want Sandy. Both services will go offline at 5 p.m. on Dec. 8. He writes: “While the company and services will be shutting down, Stikkit and Sandy’s DNA will live on; the intellectual property behind both has been acquired by Twitter, Inc. While Twitter has no immediate plans to incorporate Sandy or Stikkit’s feature sets into its core product, those who know our apps well may notice familiar-feeling bits and bobs appearing in your Twitter experience.”
