They are plenty representative of the Brooklyn of the last 10 years - that of steady gentrification and rise of cost of living, but still cheaper than Manahattan. Though not much. Much more housing stock, though.
Can we just assume that anyone commenting about Brooklyn on this post is implying South Brooklyn[1] or Williamsburg? If you aren't, please note. Something like "Come to East New York, Brooklyn" would work, so asnyder doesn't get confused.
