I did a very enjoyable talk at the Knowledge Cafe the other day. The audience was made up of various interested people, varying wildly in age – but with a majority belonging to Knowledge Management. It stood out for me in two ways. The first was the fact it was the first time I had done a talk with no slides. I gave the audience the option of having slides or not – they unanimously opted not (a lesson to learn here)! The second was that it was the first time I had really spoken about the concept that gamification can be viewed as lowering barriers.
