Maybe I have a skewed perspective after spending 4 hours in company mandated Social Networking Awareness training today, though I've always had a dim and condescending view of social networking as a whole. The little old lady with the cat is now on Facebook looking at pictures of her grandkids, who've forgotten that grandma can also see the pictures of them drunk at their first college party.
In 60 years, why wouldn't she have sent a picture of someone getting beaten up to the other people in her knitting circle (commenting, "look at the sad state of the world"), including someone who's not actually a little old lady but instead is a 24 year old market research analyst for a company that makes neoprene gloves for knitters with arthritic hands. He sends the picture to some of his friends from college, and one of them posts it to
www.worldsmostonesidedfistfights.com, forgetting to strip out the timestamp and the GSP tag that the camera embedded in the file.
Three days later, the image recognition software in your Browse program matches the picture of the victim to someone who failed to show up to make a delivery of a bag of Vory-owned BTLs, cross references the GPS tag and time stamp, and flags the video. Now, you know who beat the hell out of this guy, when it happened, and, once you find the security camera outside her building, can grab the image of the thrill seekers jumping into his car and driving away. Again, facial recognition matches one of the attackers up with his picture in an article about him winning the Academic Decathalon, which gives you his name, age, neighborhood, and the name of his high school.
