I grew up in Brooklyn and moved away 20 years ago. I go back and visit every year to see family and immerse in nostalgia. I found it funny that the neighborhoods that are so livable were among the most crime ridden ones back then.
However I do agree that you list the hipster neighborhoods and miss out on so much of the areas that made and still make Brooklyn. Sheepshead Bay, Brighton Beach, Gravesend, Coney Island. Manhattan Beach , 86th street, etc.. Each of these have their local immigrant communities, bars, local ethnic restaurant. Each generation brings a new wave with their own language, food, stores, and customs. This is the DNA of Brooklyn.
Soon enough when the cooler neighborhoods rents have risen thru the roof and the hipsters have fled to newer grounds, Brooklyn will still remain Brooklyn/
