Good write up! I wrote that part of the Like button history that Boz recorded in his Quora article about it being a cursed project when I became product manager. Those were the words the PM who was working on it before warned me with. :) Still chill me when I hear them, but not because the project took so long to launch, because of the project’s impact today. Led me to a cathartic TED talk on the matter with similar feelings of those expressed in this article. Crazy, and I did only the work at the very end of the project.
