BlaBlaCar is a social network dedicated to car pooling on long distances. It allows drivers to share information about their future car journeys and find potential passengers to reduce travel costs such as fuel costs or tolls. Each user, both drivers and passengers, sets their own “BlaBla” measurement, indicating their willingness to chat during a trip.
BlaBlaCar was started in France in 2006 and since then it has been operating in 19 countries (mostly in Europe, but also in Mexico and India). According to their site, there are more than 20 million users registered in the system and BlaBlaCar has more than 1.5 million fans on Facebook.
In each country BlaBlaCar has its own national domain, so it’s difficult to estimate its global popularity. However, the French version, which seems to be the most popular one globally, is ranked 6,736 (186 in France) in Alexa.
