Many online communities are emerging that, like Wikipedia, bring people together to build community-maintained artifacts of lasting
value (CALVs). Motivating people to contribute is a key problem because the quantity and quality of contributions ultimately determine
a CALV's value. We pose three related research questions: 1) How does intelligent task routing---matching people with work---affect the
quantity of contributions? 2) How does reviewing contributions before accepting them affect the quality of contributions? 3) How do
recommender systems affect the evolution of a shared tagging vocabulary among the contributors?
