The problem with OGAE and Eurovision fandom in general is, that it's a thing for gay men. There's hardly anyone else who occupies himself with predicting the outcome and making personal charts. Look at the Eurovision parties or at this forum, almost everyone's gay. And so is OGAE.
But the gay taste is prone to failure when the big night comes. Because Eurovision itself has a much broader appeal. On Eurovision night, there's just everyone up in front of the TV and the results are completely different. Swedish schlager or Valentina Monetta have the gay glam, that doesn't appeal to a broader audience, and that's why they are often overrated. I fear OGAE is overrating my beloved Conchita as well this year. But for the record, the best songs are still those from Hungary and Armenia, and they are dumped by OGAE.
