Maggie chose to review Pinterest for a Web 2.0 assignment because it meets three key criteria of being free, collaborative, and allowing for real-time interaction. Pinterest allows users to freely search topics, pin items to boards, and view friends' boards in real time. It also enables collaboration by letting users view other people's boards to gain ideas. The summary concludes that Pinterest exemplifies a Web 2.0 application as a free, collaborative, and real-time site that is useful for both personal and classroom use.
