Twitter and Facebook for Xbox Live will be free for Gold members, 'free trial' for Silver

This shouldn't really come as too much of a surprise, but anyone wanting to enjoy Twitter and Facebook on Xbox Live will have to pony up for Gold member subscription, the same premium prerequisite currently needed for Netflix Instant Watch and pretty much all online gaming. Silver membership will be given a "free trial," but exactly what limitations that entails, or if they'll be an option to "upgrade" to the full version, is anyone's guess.
