But would you know that if you weren't already plugged into the tech scene? I don't recall seeing a sign outside of Foursquare's building. Etsy had a handmade sign taped to some windows you couldn't see from the street unless you knew to look for it. 111 8th Ave doesn't have a big Google sign out front. There's no big Vimeo or OkCupid, etc., etc., signs outside IAC's headquarters. I don't believe Tumblr has a sign out front. In fact, the only tech company sign I recall seeing on the side of a building in NYC was Squarespace before they moved (I don't know if their new place has a sign). Compare that to walking around Soma or driving down the 101.

Most people probably have no idea there are well-known tech companies based here.
