Facebook isn't real or productive, it's just an advanced version of the electronic bulletin boards that have been around since the Internet dawned. Nobody on those old boards met their 'soul-mate' or bought a car; or paid their bills; or broadcasted their political opinions; or flamed each other for disagreeing.
Innovation is wonderful, but on its own it's not the holy grail. Other things matter just as much in creating a great company or product, most notably execution and focus. Apple excels at these things. That's why I use an iPhone and iPad. Innovation without execution produces footnotes to history, such as the Xerox Alto and Star.
