"Eu gosto, logo tu gostas"
Interessante artigo do Neil Strauss no WSJ sobre validação social e a "economia dos Likes" no facebook:
"Like" culture is antithetical to the concept of self-esteem, which a healthy individual should be developing from the inside out rather than from the outside in. Instead, we are shaped by our stats, which include not just "likes" but the number of comments generated in response to what we write and the number of friends or followers we have. I've seen rock stars agonize over the fact that another artist has far more Facebook "likes" and Twitter followers than they do."
