Well, I can't remember a year when my favourite song actually won the contest, but before the re-introduction of juries they hardly ever reached the final. Now at least some of my favourites do quite well (Iceland and Estonia 2009, Serbia and Germany this year. Estonia last year weren't as lucky, but their live performance was just horrible so I can understand that). Besides, I really do think that the bloc voting has decreased over the last few years (Turkey didn't make the final this year. TURKEY!), so, yeah, they do what they're supposed to and I'm happy.
Without the juries, ex-Soviet (like mine) countries would end up giving high points to Russia and each other, since, for example, some 30% of population here is Russians and 10 more per cent is Ukrainians, Belorussians etc. who all usually vote for their country if they decide to vote. And the remaining 60% of people are Latvians, who usually prefer Estonia, Lithuania, Nordic countries and Germany. Of course, several other countries every year receive points from us because they have great songs, but with juries they get even more points, so I can't complain.
Hadn't there been juries, we'd have given Russia some 8 points instead of 0, and I don't think we would have given Italy more than 6 points (we gave 12), so the juries definitely do more good than harm.
