I had a post which was about to pay out at $33 with 2 hours to go. I wanted to try out the promotion thing, so I threw 15 SBD at it, and now it's up over $70 with 8 hours to go. To me, that's not a bad way to use up 15 SBD. :)
Clearly, I'm a big fan of the promotion tab. I also like how it burns SBD without executing the contract for more Steem or being sold on the market to lower demand. It's a win, win, win. Love it. I also like how it creates a real world example for people who might be considering advertising on Steemit. I'm curious how often it will be used once the novelty wears off.
That's awesome that it help give your post a bit more exposure, that's an excellent use case for times like this.
It's a strategic tool to use when the situation arises :)
