Those of you who understand the blockchain and the code behind DOGE...

What can be done with this coin? What is possible?

Can it be set up like Steemit with a reward pool of DOGE? Or is that impossible?

I'm guessing it cannot be done, so I was thinking of something instead like an ad revenue sharing site, with functions like Reddit, where DOGE could be tipped also, and with the size of the community a premium for ad space could be charged and then shared according to the engagement of the members...

DOGE needs a major project to attract investors, but what kind of projects are possible or what are the limitations? That's what I'm trying to understand.
