Falsehoods programmers believe about addresses
I read this article a long time ago and I took it seriously. So instead of asking for address, postal/zip code, city, state/province, I just put up a big text area labeled "Full address" so that people have complete freedom about what to fill in.80% of the users ended up only filling in their street address, not their postal/zip code, city and state/province, even though they're from countries where (most?) addresses satisfy that format.We ended up reverting to the previous form where we explicitly asked for postal/zip code etc.
