Quite interesting they went for one of the smallest ones in this sphere and not Pinterest:

- also similar is thefancy.com.
Pinterest on the other hand took me a mere 10seconds to figure out what it was and how enthusiastically I wanted to use it.
I got tired of saving pictures of the products and architectures I liked. I was searching but I don't remember how I came across Pinterest, but when I did, I had to get in. It was early in their beta, so I sent off an email to Ben and said if you want a loyal user, let me in right now.. and he did. It was exactly what I needed!
I've been collecting all the gems of the industrial design world ever since. I even got my mom registered so she can find inspiration for her home renovation.
It's very visually appealing. None stop inspiration.
