What is *your* sourdough starter made of?

Hi Folks,

I just came across this article that describes a new "Sourdough Project" run by Rob Dunn, a biologist at North Carolina State University. The project is to study the biome (the microscopic beasties that make up our starters) and he is asking for people to sign up on this page. The goal to to look at variations in starters and what variables affect the makeup of the biome.  I plan to sign up, and hopefully learn something about my starter in the process. They are expecting to study about 3000 starters, and maybe if everyone from TFL signs up they will reach the goal quickly!
