From what I've been told, its because the company listened to the fans. People seemed to really like Derpy alot when she would show up for just a moment and do something crazy funny but she wasn't given a voice. Given all the fan art and other things that appeared after the company finely made her a normal character in the show with a voice actor as the fans wanted it. People are going nuts not only because they got what they were asking for but I think also because this is one of the very rare times a company for a show has actualy listened to the people and given them what they want rather than do what they think is best and end up killing the show. I'm not a huge MLP fan but I have to give props for whoever was listening and acting out on it rather than ignore it.

oooooh thx for explain now im understand

Not a problem. Granted that might now be the 100% reason but it is what I was told from a friend who is a MLP fan and was going nuts the day Derpy aired with a voice, everyone declared that day for ponys called Derpy day... More or less just a day to mark that the fans had a voice for a change....now if only other things would do that..music..movies...tv...the GOVERNMENT...heh, yeah I think thats asking too much.

yes agreed im not really big fan only a coy fan who have OC pony

what episiode and season was she in?

No clue. I think she popped up in the early part of season two but was just in the background really and the episode with her haveing a voice aired just a few days ago.
