Earlier quoted context omitted.
Redefine "innovation" as "generate money for VCs". Then anything which lets you sell eyeballs to advertisers (or metadata about eyeballs to advertisers) becomes innovative, if you do it at the right scale.
That's not really the meaning of innovation, though.
Whether its scale, raw idea, business model, speed, quality, or whatever; there has to be something new to get any significant traction. Are all types of innovation equal? Of course not, but all types provide some sort of value. Throw open source into the mix and you start to see the network effect in play where even "useless idea" startups provide value (although the creators may not get much return on it) in the form of assisting more useful ideas come to fruition.
