A what-should-be-obvious observation:
If both Jodah and Michelle's Facebook profiles are at the highest level of privacy, isn't that similar to past Racers having taken down their e-presence before heading out on the Race?
I can think of several Racers doing this sort of thing going back to TAR Classic (Brennan in particular with his family t-shirt business and Rob and Brennan had a site ready to go up the morning after their win aired in December 2001.)
My gut feeling is that Michelle and Jodah are that team; what are the odds of finding a potential ID of a RTacer, and then a relative just happens to look really similar to the other member of the same Race team; and then, both profiles are set to private? While it's not 100%, it sure seems to me to be well over 50%/
