Two of our core values on the &yet team are curiosity and generosity. That's why you'll so often find my yeti colleagues at the forefront of various open-source projects, and also sharing their knowledge at technology and design conferences around the world.
An outstanding example is the work that Philip Roberts has done to understand how JavaScript really works within the browser, and to explain what he has discovered in a talk entitled "What the Heck is the Event Loop, Anyway?" (delivered at both ScotlandJS and JSConf EU in recent months).
If you'd like to know more about the inner workings of JavaScript, I highly recommend that you spend 30 minutes watching this video - it is fascinating and educational and entertaining all at the same time. (Because another yeti value is humility, you won't find Philip boasting about this talk, but I have no such reservations because it is seriously great stuff.)
