Why Aren't You Sharing, Loser?

“On the social web, the person who doesn’t share is subscribing to an outmoded identity and cannot be included in the new social space. If not off the grid, he or she simply is not on the grid that matters — he may have email, but is not on Facebook, or he is present but not using it enough. (The prevailing term for this is ‘lurker,’ an old online message board term, slightly pejorative, describing someone who reads the board but doesn’t post.) It is not uncommon to ask why a friend is on Twitter but rarely tweets, or why she often likes Facebook statuses but never posts her own. Why are they not busy accumulating social capital?”
