Facebook shows us that we are all parallel straight lines

Facebook conversations remind me of these lines from Aldous Huxley's masterpiece Crome Yellow (Brave New World is rubbish): 

Parallel straight lines, Denis reflected, meet only at infinity.
He might talk for ever of care-charmer sleep and she of
meteorology till the end of time. Did one ever establish contact
with anyone? We are all parallel straight lines. Jenny was only
a little more parallel than most.
