RE: What if STEEM POWER wouldn't increase your power?
This is a fantastic idea. I am not sure I like this "better at curating" concept. Curating is just that, objective - some niches will enjoy content curated by certain individuals, others will hate this content. I think some of the incentive structures around curating will mature eventually. The cart is before the horse on this one; steem is operating far from economic equilibrium. This can be both good and bad.
I think this concept will be explored further by new communities independent from steem. The space is large. It will be larger.
Now when discussing concepts for alternative voting schemes, I think a model where steem power is consumed voting is interesting. Especially with the concept of quadratic voting implemented, see my recent post below. This essentially requires curators to put their money where their mouths are.
There are lots of other concepts that can be explored in the new attention economy playing feild. Steem is incredibly and possibly over complex. Time will tell what users want.
