This document discusses how Web 2.0 harnesses collective intelligence through methods like tagging, hashtags, online shopping recommendations, and social networking. Tagging allows users to describe and organize content, hashtags broadened from Twitter to other sites for topic filtering, and online shopping recommendations are generated from large data on customer preferences and purchases. Harnessing collective intelligence through these social behaviors provides useful information and insights beyond what individuals could discover alone.
