Last year I heard a talk by Frank Vagnone. I found out about it from an email update from Museums and Galleries NSW. The talk was looking at historic house museums, and the ideas were of relevance to many other sorts of organisations as well.
The label photographed shows a feedback mechanism which was used to explore how people saw historic houses. It was a way to learn about what people liked, did not like and their ideas for change. This is a way to encourage people to suggest ideas.
For more ideas go and read Anarchist's Guide to Historic House Museums by Franklin D. Vagnone, Deborah E. Ryan. It is a really interesting book with some great ideas about looking at history (and the need to be inclusive). I am thinking it is time for me to read it again too.
