I think you captured many of the elements quite well. You summarize and ask quesrions which is great.

In terms of your question about, "Culturally relevant about whom," I think Winn was quite clear in the spaces she studied and why she chose these spaces. She explained better than I could on why these spaces are important.

I could study the spaces in my life. Watch learning happen at the skate park, in Cub Scouts, at sports, for instance, but its would be different.

Community is the curriculum.
