I've been giving some thought to how websites are put together. Not necessarily the aesthetic design, but more of the interaction of the content and the user and I thought to ask what is the best of the web in that regard.

To steer the discussion, I came up with a few sites to offer as an example:

maps.google.com
netflix.com
facebook.com

they offer immediate feedback, yet are immersive. kinda like a video game.

anyway, what is the best of the web to you?
