This is a great initiative. I very much agree that this is needed, and I love the guidelines. I'd add that it would be great to foster communities around gaming, history, sports, programming, books and tv and others where original content is not necessarily art but reviews and discussion.
I've been writing more about steemit lately because I've been spending time digging into it but also of the complete lack of exposure when exploring other subjects. This encourages me to keep trying.
I also have a couple of undiscovered authors in my following list that I'd love to share with you. I'll drop by the channel later!
Those are precisely the kind of topics we are looking for. In fact, the more obscure and niche the topic, the better. :)
