Nothing good has ever come from Social Media. Despite all the pleas posted on Facebook to find lost children, I am not aware of even one being found. The reason for this is simple - most of these types of postings on Facebook are outdated, wrong, incorrect, or just spam.
UPDATE: Some are saying Ms. Oates was indeed in on the gag, and was trolling social media with her posting. This illustrates another problem with social media - trolling, and of course, people who believe in trolls.
But the problems don't stop there. Rumor-mongering is a big problem on Social Media. Misinformation, outright lies, slander, and whatnot are the order of the day. Mark Twain had it right - a lie spreads around the world before the truth can even get out of bed. And he said that in the age of the telegraph, not Social Media.
