I was a huge Asimov fan as a kid. He died young of AIDS (blood transfusion); one of his last books was probably his very best. The title was a winner - 'The Gods Themselves'. It was taken from a quote by Schiller 'Against stupidity, the gods themselves, contend in vain.
I thought of that quote when Citibank Visa asked me to provide answers to not one, not two, but three! (or four?) "security questions". Information only I am supposed to know. Top secret information, that will be firmly protected with all the customary security employed by banks and credit card companies to secure customer data.
Meaning I might as well publish the answers in my blog. Imagine how much easier these security questions are making identity theft. Add them all up, and there's no "thing only I know" that won't be known to a potential thief.
I did manage to keep my responses printable, though they're not at all memorable or useful. If Citibank ever requires me to answer them I'll switch to another Visa franchise.
