Just wanted to share this for new users:
The Linkedin Ansible group is a good place for major announcements or sharing interesting content or blog posts about Ansible – I don’t know if many people know about it, but it seems to give pretty good occasional summaries and won’t spam you much. It’s pretty low traffic and a good resource:

Also, there’s also a mailing list signup page on http://ansible.cc – we only send out one email a month and it contains a nice summary of news/info – including links to whitepapers and so on. See the link towards the bottom of http://ansible.cc or http://ansibleworks.com/
