I think you're right. I'm 28 and have noticed a lot of people my age complain about the UI/UX. Obviously this is anecdotal but people 25yo and under seem to 'get it'.

I personally like the UI/UX, and think it's advanced. I'm incorporating some of its elements in my own work. I for one am pretty tired of lists, lists, and more lists. I've read somewhere that the UI/UX was built in a 'Japanese style'. I dont know if that's true but it's interesting.

I think where there's room for improvement is just introducing the features and explaining how the unconventional navigation works.
