These things never just die, do they? Threads where bronies and non-bronies alike come together to complain about how overexposed they are to cartoon ponies, and they're invariably the most commented-upon threads on The Escapist. Not that I consider this a bad thing, I find these kinds of threads funny in their absurdity.
Anyway, OT: No, on the internet I only view the things I want to. If I end up on a page I don't like, or someone from some fandom is annoying me, I click a link and go somewhere else. It's one of the many beautiful things possible in this virtual world. The only way obnoxious fans could successfully shove anything into my face would be in the real world, but that's never really happened to me.
As for My Little Pony specifically, hell no. It's been far too long since there were new episodes, and I can't wait for season 3 to roll around. If you're bothered by the cartoon ponies now, I pity you. It's probably going to get much worse pretty soon...
