I've started a page up here to list people who are using Ansible.
http://ansible.github.com/who_uses_ansible.html
This is very useful to new users deciding to pick up the project, which means more contributors and all sorts of good things. I know there are some *amazing* companies, projects, and organizations using things from the Google logs and so on, and would love to see some of you listed here. If you would like to be listed, let me know by email off list. This is a GREAT way to help project momentum and also get some free advertising.
Thanks very much!
