This is how you demo your product... make it insanely easy

The site doesn't suggest what the product does. Because no trust was established with me, I submitted someone else's site, and I still couldn't figure out what I had done. I only noticed a feedback button, and I debated using it to complain about your site not working. However, after reexamining the title of your site (I apparently never normally read titles...), I'm guessing the feedback button is the product your showing off.
I'm left kind of annoyed and not really wanting to further explore your product.
(Not wanting to be entirely negative, it does seem like a quality feedback button.)
Also, please try the demo again - you'll get to see a short, targeted survey (a lead gen form) from the right bottom corner of the page.
From a usability standpoint, this technique is awesome for third-party widgets. I can jump right in, lazy registration, and try it out. I would only recommend that there are a ton of analytics tied to the whole flow to make sure you know where users are dropping off.
Currently it is nothing more than a feedback button placed on top of the page. Make this more useful.
Yes, I'm a liberal that's been mugged.
