PonyOverflow.com is a recursive joke.
With that said, I am looking for suggestions on how to successfully incorporate AdSense into my profile :)
As for your question: A pony is neither a midget horse (midgets are evil little impish creatures that eat babies) nor a brand of shoes (as far as I know).
Ponies are magical creatures that bring happiness and love wherever they trot. Their slightly smaller stature is due to the fact that they were never intended to be beasts of burden.
A closely related magical relative to the pony is the unicorn. Many have mistakenly believed that unicorns are weaponized forms of the pony, but they do not share the same body build and are actually more closely related to the non magical standard horse.
