The website helps you choose a Linux distribution that suits your needs by asking you a range of questions (such as hardware, technical experience, etc.) and then providing a list of recommendations. The helper is tidy looking and very easy to use. Considering the broad range of distributions out there a tool like this is very helpful, perhaps not for the experienced Linux user but for someone just getting into the fray....
