That was 3 hours ago and I now feel like I've got a hole in my virtual world. Its so funny that when you choose to not have something, suddenly your aware of its absence, and you miss it. I'm sure the feeling will fade ...
I do find it curious that I felt I had to deactivate my account rather than simply ignore it. I suspect it is another symptom of my desire for a tidy world with no unattended/overlooked edges!
Either way, old school email is now my contact method of choice.
(Disappointingly I only have to log back in to facebook with my old account details and it all gets reinstated ... A fact that rather reduced the drama of the experience)
