No need to post that comment here. I don't watch the show. I just draw to make people happy. If people want to see ponies, I will draw ponies.
But if you are serious about wanting that question answered: it's the internet. And it's created by Lauren Faust (who worked Powerpuff Girls, Dexter's Lab, ext.) Many people who create a 'fuss' over it are simply happy to see one of their favorite animators working on a new project. And I actually here that the show has a decent plot with developed characters, and a smart sense of humor. I imagine it has the same appeal as shows such as 'Spongebob' and 'Phineas and Ferb' and those type of shows have.
Really cool colors. I like those...uh...raindrops? Those shiny dots lined up along her legs, ear, tail, ect. Hehe. And, after snooping in your gallery, I see it is your signature style to do that. Lovely.
