My sense of design is abysmal.

Well, that's not really true. If you give me a starting point, I can probably tell you what's wrong and how it could be improved, but I cannot design something from the ground up for the life of me. I'm miserable at it. It's probably the one thing that keeps me from being productive at software.

But I know that, and I try to get someone else to help me design a UI. You'd think a company could hire at least one graphic designer.
