That's a really cool idea!! Very creative to incorporate the gaming aspect to try gain more support for Steemit!

I've thought of a similar idea before for advertising my Android application whereby we pay for a set of Xbox live gamertags and allow the community to play whatever games they want with the gamertags so long as they bring in X number of Likes on the Facebook page or Follows on Twitter, etc.

It's a win-win for everyone! People don't have to pay for Xbox live gamertags and we get more social traction. Really cool idea you've got, thanks for sharing.
