Google's Photo Spheres can sometimes be a marvel to behold, but it's not always easy to let the photographer know about it; if you stumble across a picture in the Views portal, for instance, you may be stuck. Or rather, you were stuck. Google has just added commenting and +1s to Views, making it easy to praise someone's immersive landscape shot or offer some constructive criticism. The addition probably won't turn the image hub into a hotbed of activity. However, it might get you to revisit some of these 360-degree panoramas well after the novelty has worn off -- including your own.
