Remember Your Answers? • Results based on 85 short interviews • Getting to a Web page • Using a bookmark: 57% of accesses • Typing a URL: 20% of accesses • 19% of above followed links from there • 3 out of 13 Web searches are for information that the user has seen before • 64% of searched for email is found in the user’s Inbox

  20. Results • Quantitative • Numbers, counts • Reproducible • Qualitative • Anecdotes • Building hypotheses • Categorization of behaviors
