When part of the source code was released for NXT early January, it crashed. It was depressing because I bought a lot the week before. I believe the crash was due to the criticism over the style that the code was written though.
NXT did have a big growth before the code was released in January though.
Yes, I reviewed NXT code which is awful and looks like a new programmer work, however, after the code refactoring, it becomes more and more better.
