Gringoes.com

A site I used frequently when researching Brazil and our big move was Gringoes - chock full of information directly from two key sources: expats who have moved to Brazil, and Brazilians themselves.  Content is updated frequently and is colorful and honest.  Features "Ask a Brazilian" which covers everything from exposed electrical wires in showers to the function of the police in Brazil to why Halls candies are consumed in Brazil.  Another favorite for me is the section where they feature the experiences of foreigners moving here. 

Worth a look!
