text:  I just love seeing the fans interact. A lot of these kids show up, they have liked interests, they like the same creators, they meet at VidCon in person, and they become friends for life. Oli Rodriguez, an attendee from Costa Mesa, California, explains to me the concept of cosplay. Why did you come to VidCon? I came last year and it was really fun, so I decided to come again. What do you like about it?
