That’s exactly what happened during NYC’s Fashion Week. Designer, Rebecca Minkoff decided to incorporated a large screen to showcase tweets while her fashion show was taking place. When a Buzzfeed staff member tweeted that the show had a live feed, twitter trolls took the opportunity to post obscene photos and sayings on twitter using the hashtag, #RMFall for everyone at the event to see.
Think twice before using a live stream. It may be the best thing you did to enhance the event but it could be a disaster like the Rebecca Minkoff show.
