Sadly, there is no way to do this. We may roll this out in the future -- but you're the first person to bring it up. If we see a higher demand, we'll definitely consider it.
We're planning on implementing a scroll bar -- we just don't really enjoy the default browser ones and are going to have a custom-built one soon in JavaScript.
Right now we're targeted the size to fit the majority of most common blog platforms. We'll probably roll something out soon to pass in a param to get your own sizes. The problem is resizing the analytics gets tough.
We will probably have the ability to turn on/off certain reports pretty easily if its really requested.
We also plan to implement branding VERY soon. And we're going to give it away for free. Feel free to follow @GoPollGo on Twitter for relevant updates.
Right now we're doing an iFrame because we wanted to get something out the door. The way we've built them is so that we can constantly update and polish the widget as issues arise. There is a possibility of it moving over to pure javascript at one point -- but not for the foreseeable future.
I love the simplicity of HN polls, but if you use GoPollGo, you can see votes segmented by different countries/states/district. Soon we'll be adding the ability to split votes by age/gender/browser/os/referring website.
GoPollGo is looking for talented Rails developers to help us innovate in the polling/survey space. This will be employee #3 and is a full-time salaried position with options. We're also looking for a stellar visual graphic designer -- full time salaried w/ options as well.
ActiveAdmin is quite flexible, userfriendly and has a sexy UI. From looking at http://puffer.heroku.com/admin/ I don't see any improvement at least in the UI part.
