Wondering how that barista knew your name before asking you? Check-in-based social networking game Foursquare has taken another step toward relevancy by adding analytics tools for businesses that participate. The new dashboard feature, still in alpha testing, gives data such as total number of check-ins, unique visitors, gender comparisons, and breakdowns by time. It also shows how people are sharing (over Twitter, for instance) and can differentiate between customers and staff members.

It's not that hard to imagine the barista in a coffee shop running this dashboard while you're in the shop and knowing how (and where) you spent the rest of your day. And you better hope that you don't attract the attention of a real creeper, because he or she will pretty much be able to know everywhere you've been and all the places you like to go.

I think I'm going to start checking in at strange places, late at night, just to throw people off. I can be the Foursquare bandit—dominating Wall Street late at night. Maybe there's a special badge for that.
