One of the things that really bothers me about WordPress is polls. Now there are a couple of really good poll plugins for WordPress, but if you want to make the poll as part of the blog hierarchy, as part of the normal chronology of the site, you have to create the poll in one screen then add the tags to your post. Not really a friendly way to go.
In Drupal, you create the poll, and if you have the polls content type set to appear on the front page, it'll be there after you submit it.
