Often Facebook receives complaints and heat over privacy concerns and constant changes the layout. However, today's minor tweak won't garner complaints over a layout change and, likely, won't receive complaints over privacy concerns. No, today's tweak is likely to gain acclaim, at least among the medical world.

So, what is today's tweak? Facebook has now added an option to show that you are an organ donor on your Timeline. It also provides an option to share this decision with your friends in order to increase awareness. Hopefully as people select and share this, more people will join in and make the decision to become an organ donor.

After all, 18 Americans die each day waiting for an organ transplant that never comes. "By simply telling people that you're an organ donor, the power of sharing and connection can play an important role," Zuckerberg explained. The feature is currently only available in the United States. I, for one, will be making the change to my profile.
