Update/Correction: /promoted actually is working, Not sure what I did wrong before, but I just tried again now and it worked (maybe there's a minimum amount that I wasn't aware of)? So, curators can also encourage burning by curating posts there. (the original announcement was here.)

I wonder if there is a minimum threshold and I might experiment with a few posts to see if/what it is.

The "contest" between a percentage beneficiary vs. a SBD value is an interesting one. Especially as a $2.59 transfer trumps a 25% beneficiary + $2.55 transfer. In fact, this almost certainly means that the beneficiary doesn't get promoted at all and it's purely the SBD - as can be seen by @nadiaturrina's post. Which makes sense because beneficiaries aren't mentioned in the announcement post. I could delete this entire paragraph but I won't 😆

The original announcement is also interesting in how heavily the "downvote" is promoted in order to "control garbage" too. That mentality has very much moved to Hive.

The question now is... if users follow steemcurator01's approach of setting a 25% burn beneficiary and use #burnsteem25 then their posts won't appear on the /promoted page (which I love the concept of and think that it should be... promoted). So could / should users also transfer SBD - which if sc01 starts upvoting, turns @null and sc01 into a voting bot 😆

I'll watch with interest. I've already created a webpage that monitors certain beneficiaries so it'll be interesting to see how sc01's comment influences behaviour.
