Is there a module for creating a site similar to Stack Overflow with Drupal?
I'd like to have a Drupal site with a question and answers system with voting, reputation and badges. I've found some modules but none of them have all the features.

Check out this 3 part series called Building a Stack Overflow Clone with Drupal:
The terminology is for Drupal 6 but you can do absolutely everything in that article with Drupal 7, for the most part using the same recommended modules. Also there is a release of the Answers module available for Drupal 7 which contains a fair bit of the functionality from the Array Shift module. |

That's "sort of" the point to modules: They are modular. The combination of modules like Voting API, User Points, and Achievements should get you pretty far. |

Take a look to the Answers module.
(Aswers Point module (dependency) still is pending to be ported to drupal 7, but is working in it.) |

As Clive said, there's no out of the box method for what you want exactly, but you may be able to work something with the IdeaL - idea management distribution. |

For starters, check out ArrayShift and the series of blog posts at Engineered web. |

With the EVA module (Entity Views Attach) it's possible to add a comment list to each answer with a link to create a new comment which can be added to the overlay $paths variable to create a popup form. Could be interesting. |

If you just need to integrate with your Drupal user base, you may find Question2Answer to your liking. It's a standalone system but has features to integrate with other user bases. I don't think there is a Drupal plugin already written so you'd need to write that yourself. But the Q2A software has most of the features you need (including a basic badge plugin) and is pretty extensible. |
