The setting of the work is an online community of practice focused on the use and development of a user-customizable music software package called Reaktor. Findings from the study highlight four emergent topics in the discourse related to user contributions to the community: contribution assessment, support for learning, perceptions of audience and tensions about commercialization. Our analysis of these topics frames discussion about the value and challenges of attending to amateur and professional users in online creative communities.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Jiang Yang</style></author><author><style face="normal" font="default" size="100%">Lada A.

In a Witkey site, users offer a small award for a solution to a task, and other users compete to have their solution selected.&lt;/p&gt;&lt;p&gt;In this paper, we examine the behavior of users on one of the biggest Witkey websites in China, Taskcn.com. On Taskcn, we observed several characteristics in users&#039; activity over time. Most users become inactive after only a few submissions. Others keep attempting tasks. Over time, users tend to select tasks where they are competing against fewer opponents to increase their chances of winning. They will also, perhaps counterproductively, select tasks with higher expected rewards. Yet, on average, they do not increase their chances of winning, and in some categories of tasks, their chances actually decrease. This does not paint the full picture, however, because there is a very small core of successful users who manage not only to win multiple tasks, but to increase their win-to-submission ratio over time. This core group proposes nearly 20% of the winning solutions on the site. The patterns we observe on Taskcn, we believe, hold clues to the future of crowdsourcing and freelance marketplaces, and raise interesting design implications for such sites.&lt;/p&gt;</style></abstract></record></records></xml>
