I have grown mine out too. I cut it very very short about 18 months ago, and now I have a long ponytail again. I actually find it easier to take care of when it is long. My hair is naturally curly and when it is short it tends to just go whichever direction it wants to, usually that means sticking out all over the place. At least when it is longer, I can pull it back into a ponytail and get it out of my face.
Ever 5 or 6 years I get a wild urge to cut it all off, then grown it all back again. It needs a trim right now because it is getting a bit too long and feels heavy in the pony tail.
