If you are in Australia you might have heard of GetUp, or if you are in the United States you probably know about MoveOn - but you might not be aware that these kinds of digital advocacy movements operate in 20 countries around the world. These groups are linked through a global network called OPEN (Online Progressive Engagement Network) and today we talk with Nina Hall who has written the book about how the network works!  We explore what makes these organisations similar and how their work differs across the world. We talk about a big debate inside the network - about having their campaigns between being led by member preferences and being stewarded by staff. This is a chat we at ChangeMakers particularly enjoyed as our host, Amanda Tattersall helped found GetUp in Australia.  If you have been getting emails from one of these organisations - come and have a listen to how they work!  For more on ChangeMakers check us out:  Via our Website - https://changemakerspodcast.org  On Facebook - https://www.facebook.com/ChangeMakersPodcast/  On Twitter - @changemakers99 or @amandatatts  See omnystudio.com/listener for privacy information.
