From what I can see, there's been a marked reduction in people talking to each other since this change was introduced.
Most people had a standard "greetings" key set and used it quite often. Sometimes it led to a conversation, sometimes not. Cos a lot of people use free flight, nobody wants to take their hands off the keyboard, so less people are talking. I used to greet everyone I saw and usually got a response, but that seems to have stopped, now.
