It just seemed a very good sign to me that these guys were actually
  on the ground in NYC hunting down (and understanding) their users.

That's a funny comment from paul because he was the one to tell them to go to NYC. That they went is to their credit, but still. I think of this sometimes with the pitch coaching for demo day. How many investors think "that's a great way to phrase that" when watching a presentation and what they are actually hearing is PG? When you've seen a few of them, it is quite stunning.

I don't mean this in a negative way. It actually is just evidence that paul graham is a badass.
