I'm glad you brought up communities again b/c I think we'll start to see this take effect pretty soon. It will make Steemit much more personal, enabling like minded people to share ideas and allow users with specific interests to find each other much easier. The Steemit forums (chainbb) I believe will also become much more important and popular as the community continues to grow.
The @craig-grant move is very interesting, as I agree, he has an extremely good feel and his track record really speaks for it's self. Great post as always! Have a great day! :)
