HeatRank

HeatRank is an algorithm that ranks online content by popularity. It works by rapidly measuring user engagement like comments, tweets, and shares.
10 is super hot, 1 is lukewarm.

TopicFire uses HeatRank to only show the hottest online content and filter out unpopular content. This allows you to more efficiently keep up to date on many news topics in less time. 10 is great, 1 is lukewarm. The HeatRank algorithm is different because it:

• Accurately ranks by popularity, and is less prone to gaming
• Ranks and finds the hottest news in minutes, versus hours or days
• Works with long tail topics, without requiring a critical mass of users for accurate ranking
• Is highly scalable, allowing us to do everything on 1 server

This provides meaningful advantages over older technologies such as clustering on Google News, voting on Digg, link analysis on Techmeme, or manual news editing.
