Forms in Google Docs are easy to create. You can embed forms on Web pages or on your blog, or you can send the link out in an email. It looks far more professional than a lot of free survey tools out there.
Forms feed their results directly into a spreadsheet in Google Docs. That means you can take the results and publish them, use spreadsheet gadgets or charts with them, or export the results to use in Excel or another desktop spreadsheet program. To get started, log into Google Docs and select New: Form from the upper left menu.
