Rather than just upvoting, the whales should be distributing their steem (not all of it, but a portion) to content creators to allow for more people with voting power. Right now the rewarding power is far far far too centralized to just a handful of users. This results in only a few types of posts getting valued.

It is something the whales need to consider highly, fair allotment of post reward value is very very critical to the success of the platform.
