Hi, great post and just to comment on @ond s comment. I think they generalised slightly on the 'only whales make money' comment. I'd suggest that only people with money make money here and without investment and support from big accounts, the new accounts go nowhere, get frustrated and quit. Even more so when they see the figures the top 'earners' on Steem are removing from the reward pool.
Steemit is in no way based upon quality of work, it is in most cases about playing a game which is biased towards intelligence and wealth. This also then brings in to play bias based on someones geographical location.
As you pointed out in your original and excellent post, the people who need the extra income Steem can bring into their lives are often at the most disadvantaged in their starting position.
Steemit is barely different from off chain life. It is controlled by wealth. The more wealth someone has, the more they need the minnows to survive and work to keep the platform running.
The analogy I have made before is that justvthe same as in real life whales feed on plankton. No plankton, no whales which is why the carrot of tiny reward and the hope to make moremone day isnwhatbkeeps the minnows here and new members from joining but in 99% of cases it is nothing more than carrot and stick.
As for the RC question. Its easily remedied but won't be.
Sp is delegated, this is a loan and if 50SP were delegated to new accounts on a strict 90day time limit or when theybhave made 50SP whichever comes first. There shoukd be no powerdown or withdrawals until it is paid back and this would give new accounts the time to work hard, find their way around and grow. Giving a 15sp delegation with no time limit is nonsense and does nothing except dishesrten new users and ends up stuck in an unused account when the new user gives up. A definite time limit loan always goes back to the lender and so gets recirculated. How much delegsted SP is stuck for ever in hardly used accounts? Millions no doubt.
This solution is simple, effective and will sort out the serously committed new members from the joiners who come just to mess around.
Again, great post and thanks @crypto.piotr for bringing a great new writer to my attention.
Best wishes to all who have contributed to this great thread :-)
