NYC explained BY A NATIVE New Yorker??Calling all N.Yorkers!?

ok, i am not from the AWSOMELY DESCRiBED NYC. but i need the boroughs broken down and the East side West side, Manhattan stigmas and the differences between the boroughs and the real estate/ renting prices approx. while i was told some places like Brighton Beach is predominantly Russian, and some are predominately Italian, i just need a quick but discriptive word about New York from native New Yorkers. thank sso much!
