Answer me this: Why does the interface suck so bad? How are pissing off 100 million subscribers good business? I apologize for not expanding my view with a detailed analysis, but damn. The update you guys promoted like half a year in advance made it even worse.
The interface is the result of tens of thousands of A/B tests. Every change is tested and produces greater general happiness. There is a probably a bimodal distribution on happiness, but they only optimize for the bigger curve instead of both, to reduce complexity. So while you, and an advanced user, might want a lot of advanced features, those same features scare away the majority of casual users. So it's a business…
The most annoying thing maybe is that I can't hide stuff from the lists. Like when I watch 2 minutes of something and decides that I will never ever watch that crap again - that piece of crap will forever haunt my interface.
