SRS, I think if you read back on the various threads you will find that many people wish Susan Boyle well without crediting her with a world class voice.

I, for one, hate the exploitation and manipulation of the TV show and the draconian contracts it imposes on contestants not to mention the very nasty ritual humiliation which characterizes the programme as well
I also find the cynical promotion of a 'fairy tale' by a highly paid and sucessful publicity machine distasteful and very disturbing.
Like Lox, I hope sincerely that Ms Boyle comes out of this circus emotionally intact.

As for 'trolling'.....

'In Internet slang, a troll is someone who posts controversial, inflammatory, irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the primary intent of provoking other users into an emotional response'

Now I don't consider my opinion of a singers voice to be either controversial or infalmmatory - it's simply an opinion like yours, Dons or Lox's

Unfortunately the practice or combining threads results in discussions going 'off topic' from the original posters intentions (a typical example can be seen in the recent BS thread about retaining a friendship with a BNP member)

The only examples I've seen of 'provoking other users into an emotional response' however is the name calling of people who just don't share the view that she is a 'world class' singer and the attribution of the meanest motives to them.
