What role does performance or writing space play in the making of meaning?

In todays generation the spoken word has become much weaker than in previous generations. Todays generation needs the approval of their peers and they do so by speaking with uncertainty. Words such as "like" and phrases such as "you know?" have become common to hear in the spoken word. An interrogative tone is used to make sure whats being said will agree with our peers opinions and if it doesn't agree, it is easier to back down and change what was just said.
