Use Cases

On launching BrowseOverflow, the user sees a list of topics, shown in Figure 5.1. Each topic represents a tag on Stack Overflow. Questions are tagged to indicate what subjects they address.

Figure 5.1. As a stack overflow browser, I want to see a list of topics related to iOS development.

Tapping on a topic in the list loads a list of the 20 most recently asked questions tagged with that topic, presented in chronological order. A sample list is shown in Figure 5.2. In addition to the titles of the questions, users can see who asked each question (including an avatar image) and the question’s score (how many times it has been voted up and down on the website).

Figure 5.2. As a stack overflow browser, given that I have tapped on a topic, I want to see a list of questions that have been asked on that topic.
