A site is maintained that allows consumers to suggest, comment on and/or vote on ideas about a product or service. Some site embodiments can enable sponsoring organizations (customers) to maintain their own sites for displaying articles and allowing multiple viewers to vote on these articles. Site information for multiple tenants may be maintained in a common multi-tenant system. Votes may indicate a variety of different types of criteria, such as the importance, correctness, and/or user preference for the articles or other Qualitative Management Criteria (QMC) for determining the merit of an idea or an article. The votes may be tallied into an overall Total Qualitative Management Criterion (TQMC) for the idea or article. Newer votes may be adjusted according to an increasing function of time to enable the relative weightings of the older votes to diminish over time without having to compute a decaying time function to determine weightings for each vote.
