用户参与信息描述
Tagging is when users apply keyword metadata—or tags—to resources such as
photos or Web pages within a system.
三个方向的用途（重点）
Tagging sits at the intersection of three important fields: information architecture,
social software, and personal information management.
常用的一些领域
Recent debates on tagging illustrate the tension points in most tagging systems—
personal versus social uses, individual versus standard tags, freedom versus control,
and amateur opinions versus those of experts.
价值表现
Tagging matters because it’s popular, multifaceted, flexible, and social. It’s also
made for the stream—the constant flow of information we experience online.
