Not that I've had to directly use it, but a friend of mine was showing me their university's new student center portal called SOLUS, and it's awful. It's impossible to find anything on it, and yet it's the only way to change courses, check marks, etc. It's sort of like a router interface, but harder to use and swamped with more information. The worst part, of course, is how much money it must've cost to transition this year.
