Museums are missing opportunities to utilize social media to engage visitors and crowdsource exhibit content and conversations. While some museums are currently using social media for marketing, visitor interactions, and extending their physical spaces, more can be done to turn visitors into active contributors who add and share content, direct exhibits and conversations, and become part of the exhibit themselves. However, challenges around content ownership, accuracy, and resources must be addressed. If implemented successfully, social media could create new learning opportunities, personalize experiences, and build community engagement at low cost.
