Your cynical reason defines the internet if we are talking % of content.TheGreatCoolEnergy said:Facebook.
Rational, Optimistic Reason: It contributes the least to society, considering the wealth of knowledge the Escapist and Wikipedia hold, the skill of finding stuff Google presents, and the gritty realism and honesty Youtube brings to the table.
Cynical Reason: Facebook is one big gated community of spamming, phishing, hatred, annoyingness, little kids, and wasted electicity.
