I'm not quite sure it was the point. With nearly 800 people in the room, tons of time could have been wasted trying to find out who was who and trying to find the types of people you wanted to talk to. Going up to everybody and asking them what they didn't clearly wasn't an option..so just putting the company name, or developer, designer, etc. below the name tag would have been extremely helpful. All they had to do was put an extra field for this on the YCNYC signup form and it could have been printed on the name tags.
