They wouldn't break a character completely in a kids' show. Might upset the target audience.
I like Pinkie... Just far less than the rest of the mane cast. Like Ginger I'm annoyed that she's never the one acknowleged to make a mistake especially when there were three episodes ( Swarm of the Century, Green Isn't your Color, and Best Night Ever) where she clearly exacerbated the problem. I do like her cheery and happy go lucky attitude but I just wish she didn't "win" for once.
I'm indifferent to Pinkie. The only episode that made me totally and completely angry with her was Luna, Eclipsed. That was her at her worst in my opinion.
I analyze "Geek Culture" here.
When All Else Fails, worry, that's the 14 way.
Huh. The mayor in G 3.5 was named Flitter Flutter. I wonder if that's her name in this show, too.
