Facebook’s inability to invent

Om Malik:

Facebook’s Poke app, a copy of red-hot Snapchat rose almost to the top of the iTunes appstore on launch. A few days later it has tanked, making me wonder: can Facebook really invent any new Internet behavior or is it destined to be a copycat forever?

It seems to me that Zuck did great creating the concept of Facebook, but that’s where things stopped. The ability to invent or create beyond that initial concept has escaped everyone at Facebook.
