Core of Yugoslavia, still lives on in cultural space, where music, movies, and literature are consumed in all ex republics. Except probably Kosovo, which was not part of serbo-croatian linguistic space. But even in Slovenia and Macedonia there's a significant part of population which at least understands common language. And it's not only about language, there's lot of shared mentality and history from Yugoslav period.

Sadly even Cyber Yugoslavia is no more, it only shows the text "juga.com" now:
