This is something I’ve been thinking about the whole blockchain ecosystem as a whole. A lot of the intro course are just that, and it is hard to find sufficiently advanced tutorials/training for most of the protocols out there. And while you are usually pointed in the direction of the docs, very few are sufficiently advance to take you from zero to pro. And they are more suited for reference purposes than for proper learning, anyway.
I have been planning to start an IRL blockchain academy in my home town to train developers and users beyond just « x protocol 101 », and would be interested in doing something similar with Aave if the opportunity arises.
