There is still incentive to build massive Steem Power, it's just not exponential like before. It's linear, and it no longer creates this top-heavy situation in voting power. Like I showed in my post you earlier commented on, the ~18% annual return on just one post and self-upvote per day is nothing to sneeze at in investing terms. If you can keep piling more and more money into that model without any diminishing returns and the risks are simply proportional, that's still huge. As a retail investor, there was no way to touch those kinds of returns until now either. I think eventually almost everyone involved will be happy about the effects of HF19.
Question, are you quoting something communicated by Steemit Inc. with the above formulas or are they just examples of exponential and linear functions used to illustrate a point? I haven't seen anything showing the actual formula used to calculate voting. If so, could you point us to a link showing their communication?
