Despite Facebook's plummeting stock and predominantly useless advertising, not all of the news surrounding Facebook is bad. Recently, a Facebook post saved a dog.

Beth-Andy Kohn Gresham took to Facebook on Friday, posting a photo of a helpless dog with a jar trapped on its head she spotted near her work in Memphis, Tennessee. Though Gresham was unable to physically help the dog, animal lovers responded to the Facebook post with dozens of comments and hundreds of shares. By Saturday afternoon, a team was quickly assembled to locate and rescue the stray dog.

Gresham first attempted to collar the dog herself, but the stray ran off into the woods. However, she was able to snap a photo and upload the pic to Facebook. Noting the dog's predicament and emaciated form, she listed off the names of some her own Facebook friends, seeking out their help, but also elicited an open callout to anyone in the area who could help.

While the circumstances of how the dog became trapped are unknown, authorities were able to locate the stray based on the location Gresham specified in her Facebook post. The animal was found wandering near the Raleigh Jackson Avenue off Interstate-140. Once found, the rescue team used container cutters to free the dog from the plastic jar.

"If someone tied you up and went to go beating you or attacking you, there is nothing you can do. Same thing with that dog," rescuer Jess McClain told CBS affiliate WREG. "If another dog came up and attacked him he can't do a thing, or eat or drink."

Fortunately, the team was able to find the dog in time and also rescued another stray during the extensive search of the woods that spanned Saturday morning and afternoon. The skinny white dog with black spots now has a new name -- Miracle -- and home, according to the Examiner.

This is not the first time social media outreach has saved a life. Last year, Facebook posts from a concerned mother led a friend to assist in the diagnosis of her child's rare disease doctors had initially missed.

Earlier this month, a Twitter user in London was saved by fellow tweeters who notified authorities of the 47-year-old's troubling tweets alleging a "real-time suicide."

  • Your Birth Date And Place

    While it might be nice to hear from Facebook well-wishers on your birthday, you should think twice before posting your full birthday. Beth Givens, executive director of the <a href="http://www.privacyrights.org/" target="_hplink">Privacy Rights Clearinghouse</a> <a href="http://finance.yahoo.com/family-home/article/110674/6-things-you-should-never-reveal-on-facebook">advises</a> that revealing your exact birthday and your place of birth is like handing over your financial security to thieves. Furthermore, Carnegie Mellon researchers recently <a href="http://arstechnica.com/tech-policy/news/2009/07/social-insecurity-numbers-open-to-hacking.ars" target="_hplink">discovered</a> that they could reconstruct social security numbers using an individual's birthday and place of birth. Rather than remove your birthday entirely, you could enter a date that's just a few days off from your real birthday.

  • Your Mother's Maiden Name

    "Your mother’s maiden name is an especially valuable bit of information, not least since it’s often the answer to security questions on many sites," writes the <em><a href="http://bucks.blogs.nytimes.com/2010/10/12/what-not-to-tell-facebook-friends/?src=tptw" target="_hplink">New York Times</a></em>. Credit card companies, your wireless service provider, and numerous other firms frequently rely on this tidbit to protect your personal information.

  • Your Home Address

    Publicizing your home address enables everyone and anyone with whom you've shared that information to see where you live, from exes to employers. Opening up in this way could have negative repercussions: for example, there have been instances in which <a href="http://www.huffingtonpost.com/2010/02/17/please-rob-me-site-tells_n_465966.html" target="_hplink">burglars have used Facebook to target users</a> who said they were not at home.

  • Your Long Trips Away From Home

    Don't post status updates that mention when you will be away from home, <a href="http://bucks.blogs.nytimes.com/2010/09/15/dont-tell-facebook-friends-that-youre-going-away/" target="_hplink">advises</a> <em>New York Times</em> columnist Ron Lieber. When you broadcast your vacation dates, you might be telling untrustworthy Facebook "friends" that your house is empty and unwatched. "[R]emind 'friends' that you have an alarm or a guard dog," Lieber writes.

  • Your Short Trips Away From Home

    Although new features like Facebook Places encourage you to check in during outings and broadcast your location (be it at a restaurant, park, or store), you might think twice even before sharing information about shorter departures from your home. "Don’t post messages such as 'out for a run' or 'at the mall shopping for my sweetie,'" Identity Theft 911 <a href="http://identitytheft911.com/company/press/release.ext?sp=11132" target="_hplink">cautions</a>. "Thieves could use that information to physically break in your house."

  • Your Inappropriate Photos

    By now, nearly everyone knows that racy, illicit, or otherwise incriminating photos posted on Facebook can cost you a job (or worse). But even deleted photos could come back to haunt you. Ars Technica recently <a href="http://arstechnica.com/web/news/2010/10/facebook-may-be-making-strides.ars" target="_hplink">discovered</a> that Facebook's servers can store deleted photos for an unspecified amount of time. "It's possible," a Facebook spokesperson <a href="http://arstechnica.com/web/news/2010/10/facebook-may-be-making-strides.ars" target="_hplink">told</a> Ars Technica, "that someone who previously had access to a photo and saved the direct URL from our content delivery network partner could still access the photo."

  • Confessionals

    Flubbing on your tax returns? Can't stand your boss? Pulled a 'dine and dash?' Don't tell Facebook. The site's privacy settings allow you to control with whom you share certain information--for example, you can create a Group that consists only of your closest friends--but, once posted, it can be hard to erase proof of your illicit or illegal activities, and difficult to keep it from spreading. There are countless examples of workers getting the axe for oversharing on Facebook, as well as many instances in which <a href="http://www.huffingtonpost.com/2010/08/16/arrested-over-facebook-po_n_683160.html" target="_hplink">people have been arrested</a> for information they shared on the social networking site. (Click <a href="http://www.huffingtonpost.com/2010/07/26/fired-over-facebook-posts_n_659170.html" target="_hplink">here</a> to see a few examples of Facebook posts that got people canned.)

  • Your Phone Number

    Watch where you post your phone number. Include it in your profile and, depending on your privacy settings, even your most distant Facebook "friends" (think exes, elementary school contacts, friends-of-friends) might be able to access it and give you a ring. Sharing it with Facebook Pages can also get you in trouble. Developer Tom Scott created an app called <a href="http://www.huffingtonpost.com/2010/05/24/evil-facebook-app-exposes_n_587144.html" target="_hplink">Evil</a> that displays phone numbers published anywhere on Facebook. <a href="http://www.huffingtonpost.com/2010/05/24/evil-facebook-app-exposes_n_587144.html" target="_hplink">According to Scott</a>, "There are uncountable numbers of groups on Facebook called 'lost my phone!!!!! need ur numbers!!!!!' [...] Most of them are marked as 'public', and a lot of folks don't understand what that means in Facebook's context -- to Facebook, 'public' means everyone in the world, whether they're a Facebook member or not."

  • Your Vacation Countdown

    <a href="http://finance.yahoo.com/family-home/article/110674/6-things-you-should-never-reveal-on-facebook" target="_hplink">CBSMoneyWatch.com</a> warns social network users that counting down the days to a vacation can be as negligent as stating how many days the vacation will last. "There may be a better way to say 'Rob me, please' than posting something along the lines of: 'Count-down to Maui! Two days and Ritz Carlton, here we come!' on [a social networking site]. But it's hard to think of one. Post the photos on Facebook when you return, if you like. But don't invite criminals in by telling them specifically when you'll be gone," MoneyWatch <a href="http://finance.yahoo.com/family-home/article/110674/6-things-you-should-never-reveal-on-facebook" target="_hplink">writes</a>.

  • Your Child's Name

    Identity thieves also target children. "Don't use a child's name in photo tags or captions," <a href="http://www.consumerreports.org/cro/magazine-archive/2010/june/electronics-computers/social-insecurity/7-things-to-stop-doing-on-facebook/index.htm" target="_hplink">writes</a> Consumer Reports. "If someone else does, delete it by clicking on Remove Tag. If your child isn't on Facebook and someone includes his or her name in a caption, ask that person to remove the name."

  • Your 'Risky' Behavior

    CBSMoneyWatch.com <a href="http://moneywatch.bnet.com/saving-money/blog/devil-details/6-things-you-should-never-reveal-on-facebook/2360/?tag=content;col1" target="_hplink">writes</a>: <blockquote>You take your classic Camaro out for street racing, soar above the hills in a hang glider, or smoke like a chimney? Insurers are increasingly turning to the web to figure out whether their applicants and customers are putting their lives or property at risk, according to Insure.com.</blockquote> There have been additional <a href="http://www.huffingtonpost.com/2010/02/22/facebook-twitter-users-co_n_471548.html" target="_hplink">reports</a> that insurance companies may adjust users' premiums based what they post to Facebook. Given that criminals are turning to high-tech tools like Google Street View and Facebook to target victims, "I wouldn't be surprised if, as social media grow in popularity and more location-based applications come to fore, insurance providers consider these in their pricing of an individual's risk," <a href="http://www.huffingtonpost.com/2010/02/22/facebook-twitter-users-co_n_471548.html" target="_hplink">says</a> Darren Black, head of home insurance for Confused.com.

  • The Layout Of Your Home

    <a href="http://identitytheft911.com/company/press/release.ext?sp=11132" target="_hplink">Identity Theft 911</a> reminds Facebook users never to post photos that reveal the layout of an apartment or home and the valuables therein.

  • Your Profile On Public Search

    Do you want your Facebook profile--even bare-bones information like your gender, name, and profile picture--appearing in a Google search? If not, you should should block your profile from appearing in search engine results. Consumer Reports <a href="http://www.consumerreports.org/cro/magazine-archive/2010/june/electronics-computers/social-insecurity/7-things-to-stop-doing-on-facebook/index.htm" target="_blank">advises</a> that doing so will "help prevent strangers from accessing your page." To change this privacy setting, go to Privacy Settings under Account, then Sharing on Facebook.
