Can and should, which feeds back into the "He makes 65k a month!" argument that some here get so butt hurt by. Case in point...
Is DC a scamlord? No, he's giving is quality content, but he IS damn well milking this, because he has the funds to hire more people, and get things done at a much faster rate. But he won't do that, because that would be less cash going into his pocket. Don't get me wrong, hiring 2 posers to replace the one that left is a good start, but he also needs another person for coding, and maybe a part timer to take some of the writing pressure off of Sploosh, because we've already heard how he's feeling burnt out writing the main story update and wants to move on to something else.
On a side note, I have a hunch that this is also why the game has such a hard time hitting release targets, and why .20 had to be broken up into parts. It's like DC thinks that the entire game is developing at the same speed as he's doing the artwork, when that's simply not the case.
