Leonid blogged a few times about Russian social network Odnoklassniki.ru. Basically, it’s good place to find your classmates from school, college, university or coworkers from the previous places of work. But personally I don’t like the way how it’s done and stability of that service. I found alternative service which is much better and reliable. It’s VKontakte.ru. It looks similar to very popular Facebook and offers a simple way to find classmates, coworkers and friends. It’s allows to upload photos, audio, video, write funny wall-posts, send private messages, create or join to some group. Technically VKontakte.ru satisfies the requirements of web 2.0 and ordinary users should find its interface simple and friendly.
I found a few my classmates from Military Mojaiski Academy, a lot of fun photos (black and white actually). So, I highly recommend to all Russian people check that service.
