What new thing do you think Fotonauts really brings to the table that the end user cares about? Not all innovations bring masses of users.
In no time, Fotonauts will start attracting the masses in being a reference photo site. Eg. if I want to know more about tattoos, I won't go to Flickr. I just get pictures of tattoos at Flickr. At Fotonauts, I'll get to see the photos and relevant content about tattoos.
My opinions about them were based on the demo they gave at TC50
