The American Gut Project is building a massive database of information on the links between diet, lifestyle, and individual microbial ecologies. They are crowdsourcing sample collection from people across the country to provide skin, mouth, and gut bacteria samples, which are then sequenced and analyzed by volunteers.

In order to participate, donate $99 to the project and you will receive a home sampling kit, which will be evaluated from volunteer scientists to provide you with a list of the bacteria in your sample (genus level where possible) – and relative abundance – and show you how your bacterial community compares to others in the study based on the diet and lifestyle questionnaire you fill out when you take your sample.
