Facebook


International analog of Russian social network VK [Vkontakte]. I use it quite rarely, in most cases for contacting foreigners.

Pros:
+ huge amount of users

Cons:
- heavily bloated interface
- alien logic in overall system navigation
- awful photo quality [comparing to VK]
- no personal audio library [it seems to be that this feature is not enabled due to licensing stuff]
