WinterMilestone 3 Team - Witty Improved Boomerang
Boomerang reputation system solves the problem of 'inflated rankings' very well, but it may create some additional problems. Consider a scenario where a worker did a task for some requesters, and rated them well; but these tasks were not of his interest. Now from further here, the worker will always see the tasks from requesters he had previously rated well at the top of his dashboard and his interests are not taken into consideration.
Along with the Boomerang reputation system; a 'recommender system' should be present which recommends tasks to workers best suited to their interests.
