VidCon has become an anual conference of YouTubers and their fans. It typically takes place some time in June. It is hosted by the vlog brothers and gives YouTubers and their fans a chance to interact with eachother. The first two years it took place in a Hotel somewhere near Hollywood. The third year it will be in the Anaheim Convention Center. It is the best conference ever if you are into YouTube.
person 1: I'm going to VidCon this year!
person 2: I want to go so badly! I want to meet charlieissocoollike, Shane Dawson, and NigaHiga!
