The biggest problem I'm having with pinterest is the fact that I can't see the site without getting this annoying login modal (and it's mostly annoying when it happens on mobile).

I believe they're trying to achieve continuity between their mobile and web experiences.
The "card" aesthetic is a huge part of Pintrest's brand to me. To lose that seems like a bad idea from a recognition perspective. Kind of like if Converse stopped making high-tops in favour of the more minimal, low cut. To say nothing of the functional issues.
Sometimes with design things are changed for the sake of change, is this a good thing? Sometimes Yes, sometimes No
Definitely doesn't make it easier to use. The removal of the container makes the proximity more loose and association is more difficult.
look the same as always to me... maybe they are doing a/b testing? or maybe I just don't see a difference
Ah, I see. Here's what mine looks like: http://i.imgur.com/OXhOZ8f.jpg
