Our sub-economy consists of 10 Steem, you have 9 and I have 1. You promotify your post for 3, so you have 6 and I still have 1. Or economy now consists of 7 Steem.

So with your whale promotification, you have achieved this effect:

my wealth rose from 1/10 of the economy to 1/7th.

yours fell from 9/10 to 6/7. Not counting the revenue the promotification gives you, maybe.

Promotifying posts, "burning money", is the best thing a whale can do to evenly distribute relative wealth over the economy, straightening the Lorenz curve.

Another effect, of course, that there are now only 7 instead of 10 steem, so each single steem is more valuable than before on the rest of the market of the super-economy.

This feature is pure genius, and I applaud the devs. With this implemented, I'd even be okay with an implementation of the orignal proposal I read weeks ago: let the top promotified content be advertised in the sidebar to give an incentive to burn money, IF (only IF) it turns out nobody looks at the promotified feed and whales shrink from promotifying.

Minnows should upvote promotified posts like mad to give advertisers the impression their investment turned into views and clicks, and incite them to promotify and burn money more.

I make a difference between promotion (in the chat channels) and promotification (via the promote function) to avoid confusion.
