People who create platforms like this always end up having anxiety attacks over whether or not the place is going to "grow fast enough" and the result is that they direct that anxiety at "overselling" what they have to offer... specifically going for what I call "FREE Stuff Marketing!"
In plain English, if we just promise people lots of free stuff for little or no effort, we can attract millions.
And that's absolutely TRUE! But what kind of people are these? They are the people who go around looking for free stuff for very little work. Which is pretty close to the exact opposite of people who create quality content and build social communities.
It's also why I have some hope that the current movements to build a bigger middle class here is our best hope... we have to expand the community from within before we can hope to attract the right kind of people from outside.
