I personally believe that 2 things have greatly affected P2P communications. Anonymity and attempting to hold meaningful conversation strictly through text. When we communicate with text we cut off non-verbal communications that are a major source of interpreting the intent of the speaker and the receptiveness of the listener. In-person conversations are constantly adjusting what and how things are said depending on non-verbal cues. This becomes impossible in text only communications so the words have to convey everything and word choice the dominant replacement for non-verbal cues. The fact that we are communicating primarily via text these days has spilled over into in person communication. IMHO
