It still hard to believe that one of the largest tech giants can't handle UI and UX of their main product right. I would normally assume it's an inherently hard problem them, but there is a counter-example to compare with – VKontakte, the most popular russian social network. It started basically as 1-to-1 clone of Facebook, but somehow managed to evolve into social network with one of the best user experiences I've seen. Now, I'm not using it anymore for political reasons, but I truly wish Facebook hired Vk's UI/UX folks or just cloned their design :)
