Internet publishing and blogs

Can we rely on the source? Can we trust the information we find in blogs.How do know if a blogger is telling the truth or telling lies? Is there a bias?

1. In Japan, people think Japanese foods in other counties should be checked. It is because that they think real Japanese foods should be promoted.

2. In other countries people think bringing other culture will be changed is natural. Especially palate is different for each other country, so we may change it. And it has been repetition for many years ago, then new culture created. I think it isn't wrong thing.


3. I think the Japanese page is biased because Japanese will protect only own culuture. To protect it is not wrong but right. However Japanese does it too much. Surely to teach how to cook Japanese food for foreigner is good. but I think the protect of governer isn't proper.
