I see a very complex system with hundreds of different niches. Right now it is like a big dump of all kinds of ideas but will slowly get more organized. Quality content will probably still be scarce, but will be valued and easier to spot. If this gets to the masses we can expect all kinds of things getting tons of money, from porn to 10 year old kid reviewing candy, just like other social networks.

It is a crazy real time capitalist experiment. Exciting times.
