Question is, do we really need to stop neighbour voting?
Of course, we, as fans, really hate when a poorer entry gets a better place than entries that we consider beautiful and all that, and so some fans have been complaining about neighbour voting since 1956 itself... but let me try to say this:
-The voting block most people complain about is the Ex-yugo mafia (Macedonia this, Croatia that, Serbia whatever), even more than the Ex-Soviet block (which is quite stronger and more directed towards certain countries, and actually more dangerous) or the Nordic block (pretty strong too).
-Before this year, no country had ever won from the yugo block.
Of course, if Serbia wins again next year, and they do so with an horrible song, then we could speak about the factual dangers of neighbour voting. But even with the semifinal system and all that, what really is important for most watcher is who wins, not who manages to be in top ten due to their neighbourgs.
