“…For Wiggins and Crowston [1], the more virtualized a Citizen Science project is, the greater tends to be its dependence on Web 2.0 technologies such as forums, blogs, microblogs, folksomias and other social media as a way to compensate for the physical distance from its collaborators. Prilla and Ritterskamp [29] describe Web 2.0 as "architecture of participation" as it adds simplicity of use, immediate feedback and the possibility of assessing the contribution of each user. Social software also allow users to create their identity, interact, share, build relationships, form groups, social networks and build a reputation [32], [33], all features that, when properly used, can markedly help designing virtual environments and systems that have its own atmosphere, are attractive, and provide opportunities for new forms of participation and contribution.…”
