Where is the New York tech scene, and what does it feel like? One way to find out is to take a tour. You could your tour on Wall Street, home of all the big financial firms. Or, you could begin it in the lobby of the swanky Ace Hotel. The long tables are always crowded with young, hip New Yorkers with laptops, headphones and four-dollar coffees. Then, continue on to a very different slice of the New York tech scene, found at 10 Jay Street, in an office building in Brooklyn overlooking the water.
