Thread ratings also have a significant shortcoming (in my eyes) that no-one has mentioned. You can only vote once, but the "value" of the thread may change after you've voted. Eg a thread may initially be full of rubbish, but then later some valuable info or comments may well change the tone & usefulness completely - or vice versa.
Number of views is actually a very poor indicator of the value of a thread. It is very difficult to know how good a thread is until you have opened it, causing a view to be counted.
I somewhat agree with you about the single vote theory, but if you think a thread may change in value, you can simply wait to rate it.
