When I first started reading this stuff I was thinking of going a little deeper even.
What if you could post somehow from in-game? As well as search for content using services like Steam Shovel. Huge sets of blogs could be setup ahead of time. Dungeons Masters could act as whales, in order to control the flow of things. Perhaps groups of people would work against each other in competition for resources somehow... But like... All in-game. Perhaps SBD could be generated in a timely fashion based on posts from DMs, or players, or even NPCs, like bots. All these resources could be tracked in game and move around amongst different accounts through the trading process.
I think we are just scratching the surface here and some really smart folks are going to be putting some really cool stuff together soon!
You could certainly think of posting from within game. I thought this might be picky with the current downvote mechanism I could see such posts becoming popular to tag as spam. This is one of the reasons I didn't recommend it. Then those downvotes could kill any income and chance of success for the game. :(
