Another thing I'll add, but didn't want to edit the original post:
I don't want witnesses to necessarily issue long weekly updates. I think the long updates should be limited to important updates either monthly or quarterly, and monthly may be too frequent.
The other thing is that witnesses shouldn't feel obligated to push the platform in one direction or another so long as overall growth and innovative change is taking place. We need to keep Steemit and open and accepting place of free experimentation.
