Post to a Google Plus page

Question

How do I post to a Google+ page using Ruby?

By "page" I mean one of the brand pages (e.g., https://plus.google.com/105033245922189902491/posts)

Answer 1

Unfortunately the Google Plus API seems to be read only

From https://developers.google.com/+/api/

Note: The Google+ API currently provides read-only access to public data. All API calls require either an OAuth 2.0 token or an API key.
