Implementing "Web 2.0-style" Popularity Filters

NFJS, the Magazine - June 2009

One of the fuzzy, often ill-defined requirements for a modern website is the creation of social aspects by "leveraging the community." One way this is often done is with popularity filters on website content, showing what is popular, what's hot, etc. Complexity can lurk behind these seemingly simple ideas. We were recently asked to implement a "Hot Now" filter for our client, who publishes thousands of 5-7 minute "how-to" videos online. In this article, we will use that implementation as a case study while looking at the analysis and research we did on the problem.
