Why is the MLP fandom so productive?

So, I've been studying this phenomenon for over a Jahr now, and I can't find a logical answer why is this fandom so productive (Or why I've become a pony addict for that matter)?

I've been watching tons of Cartoons growing up and I've been in many fanclubs, but I've never seen a fanbase so loyal, so commited and so creative as the MLP fanbase, in every way. So many talented artists, writers and even musicians, Du name it. Why is that so? Why cartoon pastell ponies are so appealing? Why do they inspire alot of people? Why does this Zeigen drive some Fans to become cloppers? Why ponies have become an internet phenomenon? What does this Zeigen have that others don't? Why?! Is it the animation? Is it the characters? Is there something deeper than that?

oder are we all just the victims of successful subliminal programmng?

I'm dying to know what Du think! Shoot.
