Related: Many cool collaborative Google Docs/Spreadsheets have begun here on Hacker News. It regularly impresses me when I glance at my Docs list and see them constantly updated/floating to the top (recent timestamps), getting more orderly and valuable over time.

Examples:

* The HN Contractors spreadsheet: https://spreadsheets.google.com/spreadsheet/ccc?key=0AlD_6iE...
