Slack (2013) = Pioneered… Enterprise-Grade Product With Consumer Look & Feel... When you want something really bad, you will put up with a lot of flaws. But if you do not yet know you want something, your tolerance will be much lower. That’s why it is especially important for us to build a beautiful, elegant and considerate piece of software. Every bit of grace, refinement, & thoughtfulness on our part will pull people along. Every petty irritation will stop them & give the impression that it is not worth it. - Stewart Butterfield, Slack Founder / CEO (2013) 266
