1. Goal: Annotate a webpage and/or retrieve the annotated version fast at a later time
- Subtasks:
- Annotation: edit, highlight, putting notes, etc.
- Retrieval: the retrieved annotated version of the webpage should be similar to the old one
- Environment: Potentially anywhere. Top locations reported by interviewees are libraries, dorm rooms and home
- Frequency of use: varied. Interviewees’ response ranges from once daily to once every 3 months.
- Time constraint: Highly efficiently UI to enable to fast annotation (within a few seconds) and fast retrieval
- Resource constraint: Usable on a mobile platform. One interviewee reported that he frequently annotates e-books on Kindle
- Risk: Users may lose Internet connection when annotating a webpage. Thus our system should be fault tolerant.

2. Goal: Let other people view one’s annotated webpage.
- Subtasks: publish annotated webpages, notify target users
- Environment: Potentially anywhere. One interviewee reported workspace
- Frequency of use: varied.
- Time constraint: Published annotation should be viewable by others in a minute or less
- Risk: Users may lose Internet connection when annotating a webpage. Thus our system should be fault tolerant.

- Environment: Potentially anywhere. Top locations reported by interviewees are libraries, dorm rooms and home
- Frequency of use: varied. Interviewees’ response ranges from once daily to once every 3 months.
- Time constraint: Should be easy to open existing annotations within 10 seconds
- Resource constraint: Usable on a mobile platform
- Risk: Users may lose Internet connection when viewing annotation. Ideally the displayed annotations should remain
- Implication: should display only a subset of the annotations by other users if there are many, in order to avoid information overload

4. Goal: Save a copy of the current webpage
- Example/Current practice: One of our interviewee copies and pastes useful text she finds on a webpage into a Word document if she wants to keep it. She is under the impression that webpages change all the time and fast. She is worried that if she just bookmarks/saves the page, it will likely disappear next time she opens it.
- Environment: Potentially anywhere
- Frequency of use: varied. One interviewee reported daily.
- Special NoteSPECIAL NOTE: while most web browsers already support this functionality, our interviewees' response indicate that they lack the correct model in their mind and that they are not happy to have a folder containing html files, pictures, and other files. They'd like to have a more organized and systematic way to save webpages.
