blogs and wikis

The document compares Web 1.0 and Web 2.0. Web 1.0 required technical expertise to create content and was organized through basic search and directories. Web 2.0 allows regular people to easily create content like blogs, wikis, photos and profiles, and organizes content through social tagging, ranking, and search. It describes how blogs are created through online platforms or self-hosting, and how wikis are created through editing existing ones or creating new ones. Web 2.0 content can be found through search engines, tags, categories and sites like Technorati.
