New Google Docs feature makes mass surveys easy
Forms are created in Google Docs spreadsheets via the share tab, where you'll need to make sure you select "to fill out a form." Multiple-choice or free-response questions can be added as you wish. Then add some email addresses, and wait for the responses to arrive. Survey-takers don't need to sign-in and can access the survey through an email message or a link. The responses will be added to your spreadsheet automatically.
