There are several online tools you can use to create a readers' poll. If you have a WordPress.com site, then you’ve got Polldaddy polls already built in. You can create, manage, and see results for all of your polls directly in your WordPress.com dashboard. If you use a WordPress.org install on your self-hosted site, install the Polldaddy WordPress.org plugin. Use it to get a snapshot of readers’ attitudes towards certain topics. Publish a follow-on post with your findings.
