I live on a farm in PA and am the founder of Constructor.io. We provide lightning quick, typo-tolerant autocomplete to websites. Check us out at http://constructor.io
I've noticed a trend to prevent copying and pasting into HTML fields which I find quite irrational. Doesn't accuracy increase if I'm allowed to copy and paste something? Presently, I'm prevented from copying a checking account number into a field, so I have to type it out by hand, which is much more error-prone. Does anyone know why sites do this?
