New results show that a small percentage of users of so-called social computing or Web 2.0 sites get actively involved in directly contributing to the site. An article on vnunet.com summarizes the results. A key point that is made is that most of these sites, like YouTube, Flickr, and Wikipedia have huge numbers of people actually viewing them so if a relatively small percentage of them contribute, that still accounts for some significant contribution numbers. However, it is important for those building Web 2.0 capabilities into the projects and products to keep these percentages in mind when tracking both passive and active interactions.
