communities will help create more diversity on the platform. I got to say that, even though the design is very simple and clean, there is no thoughts on increasing social share...everything related to marketing on this platform right now is an after-thought.
It suffers from what most corporate websites suffers from: "Slick website that makes no sales"
Im of the same view you can make it look as nice as you want, but if only some many people know about your site its kinda useless, That whole thinking of the end game sites do can kill a site pretty quickly.
