Social Web and Interaction: Social media technologies for museums shows that the social web can be used not only for public relations but also for interaction (museum with visitors, museum with non-visitors, visitors among themselves, museum with other institutions). With this Toolkit, visitors and other interested persons will be given a possibility to get involved with the museum’s topics, to discuss, to exchange ideas, to reflect on exhibitions, etc. It offers ideas how to integrate the possibilities of web 2.0 in exhibitions in order to promote more visitor participation.
