Poll is the latest page element in the Blogspot in nowadays. First of all I would like to give a brief introduction about the poll in Blogspot. It?s a good chance to ask multiple choice questions from visitors in your blog. So you can do a survey about your blog from the visitors.
For an example,
now I use a poll to get the idea about the requirement of this blog. I could setup the answer like ?What do you need in this blog??
Then I added few answers for that question. Those can be Blogging tips, Adsense tips, Web mastering tips and Engineering articles. Because I guess many posts in this blog are related in those areas.
As an extra feature it provides a schedule. You can decide a deadline. So you can also add a Poll in your Blogspot as a page element.
