JSON for configuration is a cute idea that doesn't scale at all. I've personally experienced this in a project at my job. Once the config gets substantially large, it becomes a headache. The real pain is when a sysadmin without any experience in JSON screws up the formatting or tries to change the config and can't decipher the parse errors.

JSON for config is a bad, bad idea - especially if your config will get large.
