BuzzFeed is sharing details about a new tech it calls Pound (Process for Optimizing and Understanding Network Diffusion), intended to enhance Web and social media analytics by tracking how a story progresses from one user to another. At this week’s NewFronts, BuzzFeed Publisher Dao Nguyen said the company is seeking beta partners to help transform Pound into a useful product. “She also talked about data that BuzzFeed gathers to categorize videos based on whether they offer information, emotion or appeal to a viewer’s identity,” reports TechCrunch, adding “that informational videos do better on YouTube, while identity-driven videos do better on Facebook.”
