“Virtual communities can be particularly powerful in delivering ROA – enhancing serendipity rather than just search. This is the highest form of ROA – finding highly valuable resources that I didn’t even know existed or were relevant to me. In this context, one of the biggest missed opportunities in virtual communities is to archive, edit and organize participant contributions. It is the most valuable asset of the community but often the most difficult to access.” (John Hagel, Community 2.0)
