Just what it means to be in “Silicon Alley” is getting a little fuzzy. Or it may have always been fuzzy, according to a piece in the Wall Street Journal. Like any self-identifying community, the precise neighborhoods that the term designates isn’t really clear. The term may, in fact, be in the process of fading from use, now in a sort of middle ground as a term for tech in Manhattan.

The WSJ writes:

Even so, the [Silicon Alley] brand isn’t entirely dead. A local newsletter, “This Week in Silicon Alley,” tracks the sector, and earlier this week New York state Comptroller Thomas DiNapoli proclaimed in a news release that “Silicon Alley now stretches from Midtown South to lower Manhattan and into Brooklyn and Queens.”

That sort of definition rings true with veterans of the city’s real-estate scene.

What is clear is that tech is growing here and looks to be part of the fabric of the city for a good long time to come. So does the term apply to Kings County or not? And does anyone really care?
