I think the big mistake that was made was the voting lines opening earlier in the day. All the "bigger names" could have gained votes earlier in the day (like Kate). These acts would also not be judged on their performance but their popularity.To be fair no matter who won I can garuntee there would have been similar comments on thier twitter feed. That us how social media works... The most negative and positve thoughts get posted those in the majority who are not incredibly negative or positive say nothing.
