For the past 15 years, there have been progressive changes in the ways people make use of the Internet. The term Web 2.0 was therefore coined to describe such phenomena. Under this new concept, the web is no longer a one-way communication medium that disseminates information to itsusers; instead, it now encouragesusers to create their own contents and to share these contents online. It is thus worthwhile for the museum sector to explore the potential benefits of the rise of the new tools developed under Web 2.0. By using various case studies, this article attempts to elaborate on the recent applications of the Web 2.0 concept in the museum sector. These case studies suggest that Web 2.0 tools are more than media for marketing, but can extend to diverse areas such as exhibition front-end evaluation, crowd-curated exhibition and platform for knowledge management. The article also point out how curators should change their attitudes in order to embrace this new concept, with the ultimate goal of creating participatory museums.
