On the other hand, theres YT which has remained pretty much the same UI-wise for as long as I can remember. And it is terrible.

I cannot search for videos about python that are longer than 1 hr. That is my pet peeve and regularly drives me up the wall. I have wanted this for years.

In addition to that, my feed is static. It's like I'm being told, "hey you, we know that you will like these and I won't show you aught else until you watch them first". Aarrrghhh.
