Messing around with the ability to auto-post photos to a site. I saw this in action the last two WordCampLAs. This could be a cool attraction for a tradeshow booth – take a photo of an attendee (maybe of their facial expression when trying a ghost pepper) and have the photos automagically post to a site’s page for the event. People love seeing their pic posted up on a site and this could draw more people to the booth. And it will drive traffic to the site.
