This seems like django with a prettier interface. As a developer, I can see the value of something like this to get something simple off the ground quick. However, in my experience, projects become complex enough to warrant actual programming in a real language sooner rather than later. Given that I'm a developer, I would not use this because I'd be better off using django/rails which will only be a little bit slower but far more flexible down the road.

The branding and graphic design are really good. Did you do it yourself, or did you hire someone? If so, who?
