1. They in fb never let you do what you you easily CAN do in vk: targeting people by sex, age, geography, date of birth, political and religious views, married/single/searching 4 dick etc., finding ANY possible content -- free books, video, music) 2. Usability (all in one or two clicks access; no one leading you in circles constantly trying to make money of you as FB does) 3. Million tons of totally free pirate content (everything they ever stole of music and video; 3rd biggest audio hosting of the planet, 4-th biggest video hosting -- if it is in english and published this and past century you`ll find it). 4. Biggest social net in Europe BTW. Main problem: mostly all around you will be speaking in russian. But if you just see movies, listen music and looking for girlfriend it is not a problem at all.) P.S. A lot of ideas was stolen by Google+ and FB from this very project.
