You're wrong. "Not too great" doesn't mean I had completely no idea about the language, I was able to spot
most obvious mistakes or strange constructions in the translation . Plus, 1,5 year later my Spanish is much better and I still think GT does amazingly good job for a machine translation. I also can compare it with how it works when translating from/to Spanish or English to/from Polish and really, English <-> Spanish is much, much better.
