Facebook is many things to many people. For one, you can keep in touch with friends near and far, old and new. The best part about Facebook is that it's easy to share information on, share links, and promote pages. And now people are using it to find kidneys.

According to Seattle news station KHOU, 36-year old Dan Garrett got a new kidney after his wife put up a message on Facebook looking for a donor. The couple couldn't find a match among friends and family, but Facebook member Aly Carr, 26, offered up hers.

Facebook isn't the only site people are using to seek help to find kidney matches. In 2011, a Twitter member with a kidney disease tweeted that he needed a kidney and 19 people offered to find out if they might be a match, and eventually received a kidney.
