Dynamics of commitment and contribution quality in collaborative communities

It is well-known that commitment is an important ingredient for contributions of high quality. With the Internet heading towards being an actionable social space, rather than a collection of Web-sites, the issue of quality becomes crucial for sharing knowledge and action in collaborative scenarios. We propose a case study for the investigation of the influence of time, user feedback and interface complexity on contribution quality. We plan to exploit different online user groups across two different temporal phases for the evaluation.
