Starting today, Netflix members in the U.S. can share their favorite shows and movies on Netflix with friends by connecting to Facebook and agreeing to share.

The new feature adds rows to the Netflix interface that show you what movies your Facebook friends have rated highly and what they’ve recently watched. If you’re concerned about letting your friends know about what Netflix calls “guilty pleasures,” you can tell Netflix not to share those details too. Netflix says the feature will roll out to all U.S. customers by the end of the week.

I’m waffling about whether this can be used positively or if it’s just another excuse for social media junkies to overshare every detail of their personal lives.
