Ninjaminers hoarding more tokens will not grow Steem.

To be technical on wording, there was really only one ninja-miner: Steemit, Inc. Everyone else who mined tokens early were simply early adopters.

We can't keep looking at the way things have been and extrapolate out how they will be in the future under the new changes. Those of us who have been working on this (for literally years now) are hoping that as a result of these changes - six months from now we are looking at a totally new Steem. Whether we can pull it off remains to be seen, but I am hopeful.

You had a choice: support HF21, or no longer be a witness.

That is 100% false. If I was not in support of HF21, I likely could have stopped it. It is a choice between HF21 and the status quo though, and I am strongly in favor of the opportunity that HF21 gives us over the state we are currently in.

I think you made the wrong choice.

Fair enough. It is quite possible I did. The results of this HF are impossible to predict, but I chose to vote for the path that I felt gave us all the best opportunity to see the platform succeed in the long run.
