CBS Labs, which has been testing new HD streaming products, has also rolled out a labs version of a new product called Social Viewing Room. The idea is that you show up to the site, pick a show that’s on right now, and watch it with your friends or whoever is there. You can comment, LOL or take quizzes for points.

The link is live, but I’m not able to see any actual shows going on right now.

Given how awesome on demand TV is, I don’t see this kind of thing being very popular. With one big exception: live broadcasts, which are by definition shown at a certain time and watched by everyone then. Apart from live content, it seems like asynchronous comments are a great way to go, as YouTube, Hulu and Joost have done.
