I'm a huge fan of the Ignite Concept: "Enlighten us, but make it quick". Most presentations are simple, sticky, informative and mostly enjoyable. One of the first Ignite presentations I ever watched is Mehal Shah's "Fighting dirty in Scrabble". I'm no Scrabble Wizard but I sure have used some of those tips, yes, heavily and shamelessly. Here is the video, Enjoy and happy Sunday!
By the way, the upcoming Ignite Morocco will be held on October. I simply can't wait, make sure you get your places today!
