“Google makes tools for everyday life — YouTube for video (entertainment), Chat (for connecting), Gmail, Docs (for business). They all have specific features and functions. Facebook is where my friends are and the functionality is almost secondary to that.”
– David Binkowski, as quoted in Tech News World on Google’s new +1 function

The takeaway? Facebook has no redeeming innovations or qualities that make you HAVE to use it, other than the fact that “my friends are there”. Well, your friends were once at the mall, the roller rink and MySpace. They’ll go elsewhere if someone builds a better mousetrap. Google provides useful tools that simplify the web experience in crucial areas of your life – yes, including search (knowledge). Can you see it unfolding now? I can. +1 just brought in your friends, web site’s analytics and social graph… Now if they can just get your friends there. 😉
