On Invaluable Resources
Names and numbers are important but invaluable resources in IT (e.g. URIs, IPs, e-mail adresses). Their consideration nicely distinguishes techies (for lack of a better word; everyone with certain technological experience and proficiency) from non-techies (e.g. management :->).
Non-techies see these resources as abundant and dirt-cheap because they do not cost any money. – Whereas techies regard them are scarce and expensive because no amount of money can completely revert a bad allocation.
