I like how pragmatic you're being. I am new here, but one of the things that attracted me to this site was the fact that much of the material is simply above my head. That's hard to find in informal public online communities outside of academia, and I feel that the very challenge of trying to wrap my head difficult material is an absolute necessity for keeping my math and statistics skills sharp. However, different people have different bars that they want to reach, and I do agree that more accessible material is a great idea. As for me, I have a voice for radio and a knack for stating difficult theories in an accessible way, so I think a good microphone will be my next purchase for my computer. Making a Youtube video or two on rationality would be a great way for me to contribute to this goal.
