|The eerie thing is that Timehop knows all this from your public postings. This gives me an idea: TimeStalk-- find out what the person of your choice is doing, in real time! Here's just a sampling:|
"Your prey" indicated on Foursquare she is now eating lunch at (restaurant) at (address).
"Your prey" just uploaded an Instagram: "Here's me eating alone."
"Your prey" just tweeted "Long walk back to my car in heels; my battery low indicator is flashing."
"Your prey" just changed her Facebook status to "worried".
Hey, it's all out there anyhow. Don't blame the messenger!
