This feature is great because it makes it simple for anyone to create a form and have it emailed to any recipient.
Before, you'd either have to build your own database, install a form application and share it with your recipients, or tediously build a form in Word. ACK!
Now, specifically in Google spreadsheets, you can design and create a form and send it to any email recipient.
When the user submits the form it automatically updates the spreadsheet with the responses.
