Services based on Vkontakte.ru

Now Contact has begun to earn! Pavel Durov informs us that the service is headed by his friend Ilya Perekopsky . The search for professional contacts is based on the contact database. Only for the time being I don’t really understand what kind of “powerful tools were developed to search for personnel on the multi-million VKontakte database”.

Meanwhile, on the basis of contact, new services are starting to produce: “In Kadre.ru” - “the fastest growing video service on the Russian Internet,” or this service also downloads video from a contact. I just received a message about the opening of a new service OpenMP3.ru . This is a very handy thing, I myself came up with such an idea ... Now it turns out that OpenMP3.ru becomes the largest collection of music files in runet.

But the most terrible thing is that the tick "Video for friends" does not save you from getting your video in the service in Kadre.ru . I hope that this is a temporary developer error ...

In general, I wonder what else you can expect from the creators of Contact and its use by other developers. Are there contact based services?
