I have concerns about all the formatting changes. I would hate Steemit to end up like Myspace - some of those designs were absolutely horrible.
Having said that, maybe there should be some guidelines/approval process for third-party skinning and theming? Not sure if this is against the prime directive, but... ya know that myspace thing.
Awesome work. Keep it up!
I don't think there should be rules for third party developers. Just let them compete freely and the market will determine who prevails and who fails.
That -might- work
