Because it's fun.
OK, I think this needs a little more explanation. With ponies specifically, the nature of pony physiology makes things much more interesting to cross over. Specifically: technology without hands, pony colorization, pony species, and cutie marks. Imagine the world of Fallout, but with ponies. Well, that sounds strange, but it is interesting to think about because of these factors (less colorization for fic, but the other three stand). How are guns used without fingers to fire them? What would the cutie marks be for assorted characters? After all, cutie marks are a visual symbolism of what makes you special, of who you are. What advantages and disadvantages of each species lead to variety that humans just don't have in the other worlds? Unicorns have magic, and the ability to use things more or less like we do. Pegasi can fly and manipulate weather. Earth ponies are stronger and have a deeper connection to the earth. What would different characters be like if they were any of these races? All of these variables make ponification much more interesting as a concept then most other fandom conversions.
Well, that and some fans are just way too attached to multi-colored horses. Now, if you will excuse me, I have to get back to my Avatar: The Last Airbender ponification fic.
