I know these things are self-selecting and statistically invalid, but I'm very happy to see the result for 'no instant messaging'.
I'm old, pretty much retired, sweated over a hot computer for about 40 years and hardly ever used it. The one exception is work, where something has to get debugged, step by step and it needs parameter values etc. Then it's quite useful, at that stage, I used whatever the company or organisation used in-house.
As for socially, I sit on the train and tube (subway) in London and watch people using WhatsApp or 'whatever' and think, why don't you talk?. I do sometimes and, of course, since old people are quite mad but safe, people talk to me too. I don't really use a mobile phone, except to solve coordination problems when meeting people, and, with the revelations of the past few weeks, I feel somewhat vindicated.
I'm not anti-tech BTW, my house is full of computers, from Raspberry Pis up to ten year old doorstops.
