TechCrunch: "Yahoo has had a busy day. Not only did they announce a new cross-branding deal with Nokia, and struck a partnership with Match.com, and had their CEO spar onstage with Mike, but they apparently made an acquisition too. It’s a location-based service. No, not that one. It’s called Koprol. Basically, it’s the Asian Foursquare.
Koprol, based in Jakarta, Indonesia focuses on the “intersection of location, community expertise and mobile experiences.” With it, people share photos and reviews of locations using their mobile phones. And yes, it allows you to “check-in” to a location."
