As a "destination discovery" system, I think this would be ok. However, I'm not really the target market. I already have ideas of where I would want to travel to, I just don't have the time or the money. Seems that a site like this is designed for someone who has the time and the money but not the ideas.... First world problems.

Personally, if all airlines in the world would magically work with google flights, I'd be happy.
