title: How to address the formal / informal speech issue?
body: <p>How do you deal with formal / informal speech when building an application that must have all its phrases in one of those?</p>
  
  <p>Most frameworks will let you pick the language for things such as form validation error messages, by setting it to something like 'en-GB' or 'fr-FR'. </p>
  
  <p>But if you want to change from formal to informal or viceversa, you will have to edit the language files.</p>
  
  <p>I know this isn't a big issue in english, but it is in other languages where you have to pick the correct word for say, the equivalent of 'You', depending on whether it is a formal or informal conversation. The same can happen with almost any word in the sentence, depending on the language.</p>
  
  <p>Any thoughts?</p>
  
  <p>Have you ever been told to build an application fully in formal / informal speech?</p>
  
  <p>Does the user even care about this?</p>
