The best ways to learn are active, whether it’s Deliberate Practice, a proof of concept demo, or teaching someone else, anything is better than passively reading or watching a presentation. And presenting at a conference forces you to distill your learning into the pure essentials, to decide what’s important, where the roadblocks are, and tell someone else what you wish you knew when you started.
But remember, you always have 2 audiences, those in the room, or otherwise watching live, those who are waiting to be inspired. And those following up after, the ones who were inspired and now want to learn. Those are the ones who’ll read your blog and follow the URLs so they can learn by doing.
