Travis, assume that a 50mm lens is a normal view. As you go to 28mm, that is a wide angle lens, and the lower the number, the wider the view. So, if you were a real Grand Canyon-wide shooter, you might go for something as wide as 10 or 20mm. However, 28mm is wide enough for normal point&shoot work. If you like panoramas, you might want something wider. If you go crazy, you will get something with a fisheye lens (wider than 10mm), but those don't get realistic results, and you won't find one on an ordinary camera.
