Your experience with Arch Linux on a production box.
tsally: Having a large organization is helpful because you have the option of buying commercial support.  I personally wouldn't go with Arch simply because there isn't a stable branch.  Rather, everything is cutting edge.  I know you can chose not to update your Arch install, but I'd still rather go with a distribution where stability is a priority.  That being said, Arch is surprisingly stable given its rolling release model.You also might want to take a look at Debian, which has a track record of being stable.  Honestly though, Debian is a bit stuck in the past, as seen with the delays in the past two releases.  They really do care about stability though.
