We had a course in the last year of faculty called "Evolved Interfaces".
It talked about cute stuff like how a menu should ideally hold no more than 7 items, a notion which I later heard, during another course, in the form of "humans have a 3-bit memory", to which I quickly crafted a reply I (very wisely) never uttered.
Evolved Interfaces is the only course I've had which mentions "Web 2.0" as a valid concept. I find that revolting.
Semi-off-topic: stupid TV commercial for Orange: "...I'm Reeves, the first too point ooh poet and I'm inspired..." bla bla. No, you're just an idiot who "uploads downtown and downloads uptown" and thinks that's so fucking creative and poetic.
Back on topic, I'm not saying that webby stuff isn't evolved interfaces, but until I can tell my light bulb "dim please" or "turn off please", and my air conditioner "computer, 20 degrees please", I'm not buying it. I mean we're in the 21st fucking century and I still can't buy an affordable, widely-available product that takes voice commands and performs useful stuff such as opening my windows (the real ones not the broken ones), flushing my toilet or heating up my dinner. Or at least changing the TV channel. And intelligently replying to queries such as "computer, tell me how that vote in the Parliament on the teachers' salary raise went". That's what I'd call an evolved interface.
