Because you don't know what's lurking and waiting for you X-periods of time from now. Sure, it works now and that's probably all that matters for most. Others like reliable solutions that won't just up and corrupt themselves at some point.

However, I've often been amazed at how "messy" code is. Code that does what it needs to, and works. Early bird get's the worm, and I applaud this guy for throwing something out (something perhaps that we were too busy taking our time "working on to get clean and perfect"). I'm sure it'll get refined and refactored as time goes by, if people latch on.
