You can turn off the hover-y box that appears if you go into your preferences and stuff. I can't remember how to do it at the moment, but I know I did it for my own journal.

Actually, the reason that hobbits aren't as affected by the ring isn't so much because of inherent goodness (the whole thing with Smeagol was that he was an odd one out in his community anyway), but because they don't want power and glory and all that stuff. They want a comfortable home, some good pipeweed, and eleven meals a day. So the ring really doesn't have much to work with when it comes to magnifying Dark Desires of World Domination.
