Answer 2

Bad Things About Friction

Answer 3

I'm an aboriginal aussie/african american... My thing is this, I've always wanted to live in Australia because languages such as Japanese & Korean are more important there (I'm learning both). I agree on fairly everything you stated above, however. There's a sense that Australia is a bit too isolated for it's own development. I'm a techie, so I love playing video games and using the internet. I'm looking to be a graphic designer/animator and I'm not sure it's the kind of skilled labour Australia wants in a migrant..... Australia's Michael Atkinson (idiot of the year) and Stephen Conroy (nutjob of the century) have scarred my view of the 'No Worries' land. The first bloke I mentioned is the one person preventing the sale of R18+ games in Oz. That second muppet I listed proposed the idea of internet censorship in order to protect kids from porn.... That's a pretty **** excuse to block an entire nation from (porn/violence) the last true DEMOCRACY on the planet! That censorship would give the government the power to block any info it wants from it's citizens. Also, it would cost millions to taxpayers to filter ISP's!! Currently this is my only problem, however, I still want to live either there or in New Zealand... Cheers!
