Wow, ~920 comments as of now. Seems to be mighty controversial. (Yeah, I know, call me Sherlock.)
Considering everything that could go wrong with a redesign of this scale, gonna say I'm actually rather positively surprised.
For instance, the grey navigation-/searchbar at the top seems a natural fit.
And, to me at least, the color palette is rather easy on the eyes, as it was in the old design.
Am I alone in not being able to get over the smartphone-ization trends in CSS design these days?
"It's called convergence! You folks with pc monitors better well enjoy those big buttons! Cause you gonna get bigger fonts on top of that! And lots of empty space too!"
Ah well, there are worse culprits out there (looking at you, Youtube).
Rant over. Keep up the good work!
