Facebook  has modified  sharing options on the Timeline to allow folks to share their organ donor status on Facebook. The company's CEO, Mark Zuckerberg , is discussing the new feature this morning on ABC's Good Morning America. Facebook users already signed up with a donor registry can add the date they signed up and have the event appears in the Timeline and "About" section of their profile, along with a personal story snippet. For the unregistered, Facebook links to a registry page, letting users sign up without leaving Facebook. According to some specialists , this ease of access (and social nudge) could encourage more people to sign up to be donors. On a slightly murkier level, the admission of donation preference on a Facebook status could act as evidence of consent, the New York Times notes. The U.S. sees 7,000 deaths a year due to lack of access to a transplant, compared to 18,000 deaths a year  from AIDS.
