Well it wouldn't be random the way I was thinking of it. We could have a minimum amount of time it gets to stay up there then when the next person (in a queue) submits their screenshot it becomes the profiled screenshot with caption and description kind of like IOTW/D, etc but without the pretense that it's a specific amount of time. IF there are no more submissions for a while the last one sticks around (including the time period its given to stay up there) until someone submits a new one.
