Abstract: A content unification system is described herein that aligns related content from various sources into one unified stream. The system leverages tagging (e.g., hashtags or other added metadata associated with content) to filter and connect related content across sites, formats, and sources. One component of the system is a user-friendly and customizable “dash board” view of the various topics, called a “tagboard”. Tagboards can be quickly and easily created by users and can be embedded on any website. Users can interact with various content sources such as blogs, forums, or services without leaving the tagboard they are viewing. The content unification system provides users the tools to make the web efficient, increase user interaction, and increase the signal to noise ratio. The system also allows site owners and publishers to monetize their traffic better by directing advertisements to their content in real time.
