Koprol allows users to submit photos and reviews of places they “checked-in” using their mobile phone. There’s no mobile app tied to it and your phone just needs to have a browser to connect and log-in.
Indonesia is a huge market in the mobile world (BlackBerry is equally popular) and it’s not a big surprise that they have their own home-brewed location-based community. The fact that one can use Koprol using the phone’s web browser is an advantage that allows the site to be accessible from a wider set of mobile handsets (not just smartphones).
Yahoo! did not disclose how much it bought Koprol but it surely is way cheaper than the $100 million they allegedly offered to get FourSquare.
And while FourSquare is slowly becoming popular among Filipinos, the Indonesians must be proud to have their very own site snatched up by a global company like Yahoo! The closest I can recall that could have matched this milestone would have been eBay buying into Sulit.com.ph (inside source told me they had talks a couple of years back but didn’t materialized).
