The Social Network Integrated Friend Finder (Sniff) can be accessed by Facebook or cell phone and is already popular in Scandinavia. Sniff is run by Useful Networks, which is owned by Liberty Media.
Sniff says only consumers who give their permission could be electronically tracked by the service and plans to charge users about 75 pence in the UK (about a buck) for each location “sniff”, with the results for mobile customers sent by return text.
It looks like the first Facebook application to apply premium charges to customers’ mobile bills.
In many respects, it’s not unlike what Loopt is doing with its friend-finder features, but the Facebook aspect looks like a new twist.
