Don't agree with your conclusion, @sigmajin but, you brought out some interesting points in a constructive way in this particular comment.
Therefore, upvoted that particular comment. Having said that:

1. You erroneously assume that I have contempt for whingers. Since, I gave you that impression. I apologize.
2. User base: Without sticky users, there is no Steemit. Agree with your conclusion but not with the extended ad hominem.
3. Bought in: I've not bought any crypto for fiat. I've "earned " Steem or crypto. So, I cannot comment on a trading/capital gain/loss of the Steem crypto currency.
4. I have not seen the blog post by @ned that you reference.
5. Thesis: Even if a few are making or in your opinion have made outrageous profits, the fact remains that without them we would not have that as a topic to discuss, debate or disagree on. I am grateful for the opportunity to participate, on whatever level, without a focus on what someone else is earning, at any level.
   Would like to thank you, sigmajin
   Your enthusiasm has given me some ideas for some fresh posts.
