The poll is _HUGE_ (it takes up a 1/4 of the screen with redundant information (why is there a button and then a giant blue box right below it that says the same thing as the button?)
You can't create polls within your site, you have to go and make them on their site then copy/paste the code into the editor.
There is absolutely _no_ customization other than poll questions. The button color scheme is atrocious. And again, it takes up WAY too much space. I had two questions in my poll and it took up nearly 1/4 of the screen.
There's an upgrade option to customize, but you have to email them, which is bizarre for a web service.
