I watched Frontline's "Generation Like" a program that explores how the perennial teen quest for identity and connection has migrated to social media — and how big brands are increasingly co-opting young consumers’ digital presences.
Sure - conceptually what we like (what we watch, eat, read, people etc.) defines our priorities, our purpose and over history builds our memories and our life experiences. But my likes change constantly and what I "liked" a decade ago bears no resemblance to my "Likes" today.
So it could be that "Likes" are transitory and what matter is what we "Love".
Maybe that's the next Facebook App - Love
