Great read, thought this bit was spot on:
" 4. Destination site thinking replaces platform thinking.
A major symptom of the frenzy to monetize is that previously platform-centric products are reverting to destination-site thinking. Twitter’s adoption of media embedding, Instagram’s decision to pull its content from Twitter, Facebook’s launch of Poke and Google’s failure to add a write API to its G+ platform all display an “own the user” mentality. AdSense and AdWords would never have been invented had Larry and Sergey not understood the value of providing a monetization platform for others to benefit from, even for users not on Google. This is the type of thinking required today but currently all roads point to several varied attempts to re-portalize; that is to say, to own your own traffic and seek to monetize it. This is the old Yahoo view of the world and it clearly represents a limited mindset that will not scale to the huge mobile opportunity. "
