I have discovered Foursquare. Made a profile (sorry, no pic yet) and connected it to my FB and Twitter accounts. I let foursquare detect all my friends who use it and added them. I looked around on the site, tried different things and then moved to my phone. Places nearby: a tram stop, a supermarket, the local vet, Maarten and Kris, one of the local mosques. Wait, who are these Maarten and Kris guys?
The full address is listed. The place has a mayor. I checked his profile. The guy checks in at two locations: his home and his work. And suddenly I got curious – I already have the guy’s address, how much time will it take me to find out his phone number, place of work and date of birth.
Foursquare: home address, first name, FB profile, work, 3 friends. Facebook: surname, studies, work confirmed, relationship status, 85 friends. Use name and surname to find Twitter profile. Twitter: website of the sport society he is active in. Website: e-mail address and cell phone number.
5 minutes. I didn’t bother looking for the date of birth – got bored.
Now tell me – why should I use Foursquare?
