Completely new to me, and extremely easy to implement are free polls from Pollhost. You can have a poll up and running on your blog withing a few minutes. Just open an account, create your first poll, generate the HTML, and paste it into a Blogger Beta html-page element.
You can have up to 15 polls running, and each poll can have up to 20 answers.
So, let me know which hack is most usefull to you. And if you like other polls, please let me know!
