Dulwich OnView (DOV) is an on-line blog magazine associated with the Dulwich Picture Gallery (DPG) in south London. Uniquely, it has been set up by some Friends of DPG in the local community, with a symbiotic relationship between that community and the museum. DPG benefits from the marketing and publicity generated by DOV. DOV benefits from the status that DPG brings to it. This paper explores recent developments of DOV in the context of its community, including a study based on the Community of Practice (CoP) approach and a usability review for a planned redesign of the Web site.
