I've recently fallen head-over-heels in love with YAML.  Specifically, I'm thinking of configuration files -- I hate the non-standardization and slightly-different-syntax configuration files that exist for thousands of programs.  I've gobbled it up for my own teensy projects.

But AFAIK, the usage/take-up of it seems way out of kilter with how much it promises and how much talk there is of it around.  I've tried to find a list of //significant// applications that use YAML for config.  The only ones I can find are:

* RoR (barely worth mentioning)
* Symfony
* Python App Engine

So, my questions: are there others?  If not, why not?  Is there a single example of an existing application that has made an effort to switch its config syntax to YAML?  Within the context of configuration files, is there a significant competitor to YAML with the promise of standardization?
