1. Why do forms that expect a credit card number reject spaces?
When you enter a credit card number in an online ordering form, it
would make sense to enter the groups of digits with spaces between so
you can easily see if you got them right. But no! As soon as you hit
Next, the form clears and you get an error message about an invalid
card number. Developers: how fucking hard is it to ignore the spaces!!
Assholes.
It's trivial and it's exactly what I'd do. I also dislike forms that
split the CC number into four separate inputs, then when you type your
fourth digit it automatically shifts focus to the next field. All very
good until you make a mistake and need to backspace.
Well as long as we're complaining...
Another *very* common mistake is making the user select their state
from a long drop-down list instead of just typing in the two-letter
abbreviation. Jakob Nielsen pointed out this was bad web design over
TWELVE YEARS AGO and still only a few get it right.

Most forms appear to auto-fill when you type the first letter. They're
alphabetized by the full state name rather than abbreviation, so you
have to hit 'N' seven times to get to "NC".
