However, it’s not a realistic scenario. All you know is that Random_Joe is at some restaurant or cafe. You don’t know where Random_Joe lives. So how can you rob him?
Enter Google Buzz (GOOG). And this is scary.
Every once in a while, I’ll check out nearby buzzes on Google Buzz Mobile. Usually it’s some harmless comment or random conversation. Sometimes it’s a helpful tip or review on a restaurant. On a few occasions however, I’ve seen people buzz from a residential location, presumably their home.
It’s not difficult to guess what you can do from there, especially if they haven’t limited their privacy options on their Google Profile. Yup, you can monitor their buzzes, learn about their habits, and even know where they are (and when they’re not home).
Methinks PleaseRobMe.com should switch their Foursquare feed with Google Buzz.
Fortunately, it looks like only a few people are doing this right now. I imagine using your mobile phone to buzz from home isn’t a common use case, though it clearly happens. Perhaps this should be a new best practice: Don’t do anything online that can share your personal address and your current whereabouts to strangers.
P.S. I also once saw a guy buzz about how much he hated dealing with customers. And he did this from his work location, a car repair shop. Guess which shop I’ll never go to.
