What Debian distribution should I use?

There are currently three Debian distributions:

stable: This distribution is the most tested and is officially supported by the members of the Debian community. Each time a security problem appears, a patch will be made available as soon as possible. This version should be installed on production servers.
unstable: This is the distribution used by Debian developpers. As the name shows, it may be totally unstable in the sense where sometimes services will not function correctly. However, security problems are usually dealt of with very quickly.
testing: This distribution allows Debian developpers to test what will become later the next stable distribution. A package installed in testing should be available on all other architectures supported by the Debian project as well. However, no effort will be made to fix security problems in a timely manner, because of lack of resources and because of contradictions with the goals of testing.

To be clear: unless you don't care about stability or security, you should be using ONLY the stable Debian distribution.
