Drupal Views is a powerful module. The ability to generate lists of things in Drupal means that it is used everywhere. It even has a powerful plugin system that allows other modules to interface with it and create more functionality.
With multilingual sites there is a common issue I come across quite a lot that is quite easy to fix. A View will be created (usually via the Views wizard) that is intended to list a type of content. When an item of content is translated the content is duplicated in the View and you end up with a single list containing both translations of a single content item.
