They've been going 100mph for years now. It doesn't come as a surprise to me that they haven't gone back and made it pretty.

While not even remotely on the same scale, I just spent 3 weeks building an app as fast as possible because my client's old one was causing 75% of their support calls. The code isn't pretty, but it works and it works a lot better than the old one. I know deep down that code is going to stay ugly for a while but that isn't what's important right now.
