If MLP goes to Nick then Discovery Family will be on life support. I mean besides MLP all they really had was Transformers and a dozen super forgettable reality shows.

As for Pony Life itself I'm more or less okay with it since MLP:FIM had a proper ending and ended well unlike Teen Titans and the old Thundercats show. So they've kinda earned the right to a goofy parody show. Besides it's clearly fluff to fill the void until G5 starts in 2021.
