Last night, the Cooper Square Hotel Penthouse was the site of the joint holiday party of its friendly neighbors: Curbed, Hard Candy Shell, Foursquare, (who all share an office at 36 Cooper Square) and Brew Media Relations. Let's take a look at the folks that made it out to toast the techies that took over the Village Voice building shall we? 

The party hosts! Hard Candy Shell's Kevin Kearney, Curbed's Lockhart Steele, Brew's Brooke Hammerling, and Foursquare co-founders Dennis Crowley and Naveen Selvadurai.
