Months ago, Facebook acquired Glancee, a small company that had developed a smartphone app that used smartphones’ GPS information to locate people. Facebook renamed it Friendshake, while they tested it within their Facebook mobile apps. In June they renamed it “Find Friends Nearby” (FFN) and quietly rolled it out.
The FFN app was quickly dubbed “the stalker’s app” and within 10 days of release, Facebook withdrew it. You can see if it works or not by going to www.fb.com/ffn.
I’m surprised that Facebook and other social networks can change their games’ rules, as the games are being played. What sort of Terms Of Service (TOS) have Facebook users signed? Apparently it’s a carte blanche.
