Facebook is a place to catch up with friends, share articles and information, and now find kidneys.

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

Acts of generosity like this have been popping up more and more on social networking sites. In fact, according to the French Tribune, organ donation groups are becoming more common on Facebook, with about dozens of pages available under the search term "need kidney."

Facebook isn't the only site people are using to help find kidney matches. In fact, in 2011, a Twitter member with kidney disease tweeted that he needed a kidney and 19 people offered to find out if they might be a match — and when the match came back positive for one of his acquaintances, he received the kidney.

Meanwhile, a woman in Florida recently received a kidney after posting an ad for one on Craigslist.
