Google docs: Conducting a survey

If you go to http://www.google.com, you can access your account with the email address and password you use for Blogger. From there you can access your blog, a Picasa album and other services, one of which is Google docs.
So, click on docs and you'll see that you can create different kinds of documents or even upload them from your computer - you can upload html too!. Then, they are saved there and you can send them by email to other people or embed them on your blog.
Two kinds of documents are interesting for me, the forms and the spreadsheets. These two kinds of documents allow us to conduct a survey from our blog and then publish the results on a spreadsheet.
Today I'll explain to you the first step: How to create a form?
As you'll see, it's very easy: You give it a title first, you click on add question, every time you want to create one. Then you choose the type of question - multiple choice, ticking from a list, ...-, you fill in the gaps with the possible answers and finally click on done and save.
Then, you may copy the link or the embed code, which you can later paste on a new post in your blog.
