The team members aren't machines, you know. They're people with families and issues that tend to get in the way of projects like this. In fact, if I recall correctly, Katie just recently had a baby. And, like the Nostalgia Critic said, anyone who thinks being a mother doesn't make a hard-working responsible woman clearly has never been one. Also, while the first four episodes were a little on the short side, I'm pretty sure they took a bit of time and effort to make as well.
