I signed up for Google docs & spreadsheets as "stretchtherabbit" again.
This is the first time I've ever used Google docs and spreadsheets and it looks pretty useful. Say you're a student and you writing a shared paper with a group. You wouldn't even have to meet with your group members to work on the paper. Everyone could work from their own location on their own computer and edit the paper as needed.
This could be very useful in the library if a group of staff needed to work on a project together. Instead of emailing back and forth and asking "what do you think of this?" or "how does the wording sound?" and attaching the document, everyone could view it and makes comments and/or changes.
