50/50 rewards certainly isn't helping that.

75/25 encouraged me to buy stake, write a few posts a day, upvote my few posts, use remaining upvotes on others, continually restake my earnings, buy more stake, repeat.

50/50 rewards encourages buying stake, following any active curation trail that uses 20% of daily voting power, never writing any posts, profit for nothing but keeping HP staked.

EDIT: Would like to add the following.

75/25 typically would see more value from whales being drained over time out to who they upvote. In a few extremely rare cases some users on Steem upvoted themselves 10x a day for almost no effort, that didn't consume much of the overall rewards pool though. For example, a whale with 1 million SP and lets say they have 1% of the total Steem at the time. Over the course of a few years since they are giving out 3x more than they are taking in(75/25) they might only be .5% of the total Steem now(not counting inflation). In the long run the whales are less and less stake.

50/50 this is not the case, whales are able to maintain being whales. 50/50 is a total embarrassment.
