Why exactly would it be lunatic not to use Facebook? I "deleted" my account about 18 month ago to no ill effect, whatsoever (except having more time for more worthy ventures) I really don't mean to take the piss on you, but I'm constantly surprised in how people perceive Facebook and other social networks as an absolutely essential utility. Like phone service, electricity, water, or even financial services. I vehemently don't feel this to be the case.
