This can worth a try, but we need something more at a long-term. Steemboost was a step in the right direction.

How can you promote a platform? With happy users.

How can you have happy users? By rewarding their activities.

How can you reward their activities? LACK LACK LACK (like any social media).

Steemboost was the FIRST step into the world of article sharing, article promotion and so on. If that will work, we'll have a stronger community with stronger individuals willing to help the promotion of Steemit.

For example: would you promote steemit if your earnings stay as low as 0.50$/post? It would be nonsense in my country, for example, because you can get that amount of money from a lot of websites.

People don't always get the "coolest" part. But they get the exposure of their contents. So we can try to figure out how to give that exposure to them.

Hope that'll help :)
