You will be pleased to know that EK have just hired a group of people in Dubai dedicated to social networking. This is a step in the right direction...
As for wanting to choose a seat mate via FB or LinkedIn, that's another matter entirely. Firstly, I don't have a FB account (and never will) so that's a moot point.
My family keep telling me that I am getting grumpier as I get older - and most of the time when I travel I'm asking staff to block the seat beside me, rather than find me a cute seat mate
