Just curious -- when I refresh a random SE site's home page, I see a message in my JavaScript console:

[18:50:38.128] De verbinding met ws://sockets.ny.stackexchange.com/ werd onderbroken tijdens het laden van de pagina. @ http://cdn.sstatic.net/js/full.js?v=ee8dc25807f6:13

In English, that would be something like...

[18:50:38.128] The connection with ws://sockets.ny.stackexchange.com/ has been interrupted during the pageload. @ http://cdn.sstatic.net/js/full.js?v=ee8dc25807f6:13

What is this web socket for?

Websockets on the Q&A site proper are used for live updates to the homepage and for live updates to questions, answers, and your inbox. The chat subsite (http://chat.stackoverflow.com) also uses websockets to implement the live chat function. The chat subsite does use websockets, but I'm not positive of its actual function.

This feature has been implemented for a while now. You can check for new features here: Recent feature changes to Stack Exchange
