Also, the All Users shows a different perspective with many, many new users with miniscule stakeholding joining, which skews things. Active 24 Hours eliminates the effect of inactive users.

The attrition rate of signups becoming permanently inactive appears to be about 80%. Replacement by new signups (especially if rate of those are growing exponentially) masks the attrition rate. I hope you can shed some light on this, even if it is not favorable for Steem.

Why do you compare only active 24 hours users and their stake percentage and not all users? Because I saw another statistics here: http://steem.link/egiWt

There we can see as percentage of all the money supply including abandoned accounts that the GINI coefficient may not be improving much. The very high attrition rate coupled with the voting reward algorithm which quadratically favors whales inhibits rapid redistribution to a normal power-law distribution of wealth.
