I'm not really interested in the service but I did look through the FAQ. The link to Gravatar is broken, looks like an autogenerated link, so you might want to check all other external links too. Back button is broken on the FAQ page. Also, why not have the answers on the same page as the questions and have a list of questions at the top instead of this ajaxy hide/show thing. It makes reading multiple FAQs a pain with too many clicks on shifting targets and breaks the back button. Also the frontpage seems very slow and loads stuff from facebook, which slows it down further.
