Personally, I find there is some logic in the way it currently works. You have to click on your name (= representing the “account”) and log out is at the bottom. I agree with most which have been said above. I think it’s great like this, but I can understand that some people may have troubles to find it the first time (and it would be unfortunate if they need to log out from a public computer).
This may be a good thing, even if less is usually better (why have additional ticks and stuff which aren’t needed !?):
