yes, that's in concise an essence of the "Engage" guide! :)
I wish I could have find it when I needed in the beginning.
had to figure out these things on my own.
later on have also written similar personal realizations :
"Curate or Perish", "Engage with people". "Change is within".

personally I've got an experience of community's help and support in practice. without it I won't be able to post as regularly now as I would wish. so, yes, community here does matter! :)
