The phenomenon of vkontakte.ru or how to shoot away!

Crazy dynamics! A month ago, I visited the site vkontakte.ru and found a huge number of old friends there ... the service was very interesting!

The dynamics of the project were the most striking, as I understood the site for just a year, and he had already jumped around such old resources as Yandex, Rambler, etc.… Mail.ru was recently valued at a billion dollars!

What do you think about this startup?
