Catnip for me: the first post in a new blog that tells the story of building Slack from the ground up, by two of its former employees.

This was surprising to me, although I guess I don't really know why: "We used the tried and true LAMP stack (Linux, Apache, MySQL, PHP). We were all deeply familiar with these conventional tools, and Cal and the Flickr team had defined a framework for building out and scaling web applications using them (called flamework for Flickr framework)." #Technology
