I greatly miss the whitespace. When I visit my photostream now, I am presented with an entire screen full of things to process. It used to be about enjoying a single photo, but now the experience just feels like "look how many photos I have".

Sure, it's hard to please everyone, but it's hard for me to personally transition from the old layout.

That said, I'll keep my paid account around for awhile if things keep evolving for the better.
