In addition, groups of contributors to different information systems can be driven by different motivations. Huffaker and Lai  examined workers’ motivations for contributing knowledge at IBM. They found that new and younger workers were motivated by achieving recognition from the management, whereas older workers and workers who had worked longer for the company were driven more by altruistic factors, such as a desire to provide mentorship and help the community. Oreg and Nov  found that contributors of open source software were mostly motivated by reputation building and self-development, whereas contributors of open source content were driven more by altruism. Moreover, activities in RIMSs that involved targeted sharing of information with specific researchers could be viewed as forms of collaboration (e.g., answering questions). Stvilia and colleagues  found that when deciding whether to collaborate with another researcher, researchers gave priority to their intrinsic motivations, such as the quality (i.e., interestingness) of ideas a potential collaborator might have.
