Move back! One of the best ways to eliminate shadows is to move further away from your subject. This allows the light to be distributed more evenly throughout the room and bounce off more walls before reaching your subject. I use a Stofen indoors with good success as well.
...actually quite the opposite is true. A light quality on a subject gets harsher (more defined shadows/hard edges) the further away you are. Also the smaller the light source the harsher the shadows as well. So just by backing up, but keeping proper exposure, is going to make your shadows worse, not better. The closer the light source is to your subject (and the larger) the more 'wrap-around' effect you get which softens the shadows. I know this sounds counter intuitive to most people but it is true.
What i think you were getting at is only when bouncing a flash. Then further back would make it better and i agree. Here is why.... given the item you are bouncing off is the same distance to the subject but you move the light further away then that item you are bouncing off of will receive and distribute a wider more diffuse light and therefore soften the shadows. So in effect you are just make the light source bigger. And bigger is softer, given the same distance.
Now if you are moving back and now bouncing off the ceiling instead of being in close and shooting direct, that's another story. But all things equal... more distance equals harsher light/shadows.
Think about it. Given the same angle and proper exposure a light source striking a subject further away will be less able to bounce light back into the shadows because of fall-off from the surfaces it is bouncing off from. Put the light source closer to the subject and the bounced light from the surrounding environment is also closer and more able to bounce light back into the shadows thus softening them. This is why in studio shots you will often see big softboxes and they are placed relatively close to the subject, you get more wrap-around than if they were further away.
