@o1eh, I think this is actually a good thing because the idea is to put the idea of Steemit in front of as many people as possible.

Curiosity is often what makes people decide to check something out. And I think "grassroots" always will be more effective than a company advertising. It feels more trustworthy. I know I certainly am more likely to try something if a person I follow on social media recommends it, rather than from seeing advertising.

It's not easy to measure in the immediate sense. Some years ago, I used a targeted Facebook campaign to get more people to "like" my business page. It cost me 100 USD, over a month long period... but I ended with 2200 new followers, quite a few of whom engaged with my content... and over the next 4-6 months definitely paid for itself many times over, in terms of increased sales.

On this post, you have Steemcurator support again... so you'll end up with another 15+ SBD or about 60 USD. Might be worth it to use some of that and try again... maybe divide the money into two and experiment with different tags for each half?

It all helps!
