Just like last.fm, Xbox 360 owners looking to socialize with friends on Twitter and Facebook via Xbox Live must have a Gold Membership. Just a little nugget that popped up in the price cut announcement from earlier that we thought you might want to know about.
Xbox LIVE Gold Membership will be required for Twitter and Facebook when they are available, and is required for Netflix. Games, media content and Netflix membership are sold separately; a hard drive is required for storage.
