The website enjoyed spectacular growth and success, and one 2009 study called it a "model example of the ‘rags to riches’ ideal of an enterprise construed with no financial funding and no institutional support (neither from ASP/ISP corporations nor from central/local administration)".[4] Specifically, as of 2009 the service had 13.5 million active users.[5] ranks among the top five Polish social networking portals, behind,, and Wirtualna Polska, and it attracts more than 50% of Polish Internet users (10% of the traffic comes from abroad).[4]
