How do you get 10,000 people to hate you?

It is 11,400 registered users to be exact. This has got to be the most interesting piece of news that I've ever seen on Javno.com (a news portal in both Croatian and English). Apparently, there is a registered group on Facebook calling for 10,000 haters of Ivo Sanader (the Croatian PM) to join it. The end result was more than what the administrator of the group expected. 11,400 users joined it. There was even a date for an official protest against the PM. The PM was furious of course and called this an act against the government. Now I wonder how many will turn out for the protest this week?

Here's the news link for those interested individuals!
