I will only quote one thing for now
"3. People Are Learning Through Commander
This is something I never would have anticipated saying a few years ago. But it's true: everything we're seeing shows that a lot of players are actually coming into Magic through Commander. (Or at least picking up Commander very early.)
For a long time, we had considered the format an anathema to new players, full of complex interactions, every single mechanic, and tons of cards to keep track of. I mean, somebody could even cast a card with banding! We have generally tried to point new players to other places."
It then says "Fortunately, despite Commander's complexity, it's actually great for teaching in many respects because it's multiplayer and totally casual. People can help you through the game and provide suggestions, and you don't need to understand everything that's going on to understand the game."
I have personally learned more from Commander then any other format. So many interesting interactions and to see/watch all those interactions as they transpire compared to anything else. Then it is so much fun to drop out a card onto the field and have someone go "what the heck does that do" or "what the heck is that".
LOl enough out of me for now
