Google Trends shows how often up-and-coming Brooklyn neighborhoods have been searched for on Google.
First, a snapshot of some of the already-hip and soon-to-be hip neighborhoods in Brooklyn: Greenpoint, Red Hook, Bushwick, East New York, and Gowanus:
Second, a celebrity death match pits Gowanus against Red Hook:
So, while Red Hook has been in the news for a while now, Gowanus has just hit the big time in the last few months. The uptick in Red Hook's hit pattern in the middle of 2005 probably corresponds to the surge in news coverage of the Ikea site. (It's also worth noting that there are a number of "Red Hooks" nationally, including a town upstate and a brewery in Washington, so the appearance of hits for the Brooklyn Red Hook is somewhat misleadingly inflated.)
Also, who's writing about Brooklyn? Well, mostly us. And it looks like the Polish migration to Greenpoint is alive and well.
