I'm a really visual person, so I love making diagrams to explain my ideas. Unfortuantely I can't "think" while i'm typing. In fact, I can't really think while I'm in front of a computer. I usually draw everything out on a dry erase white board.
This could solve my second problem, which is to take my drawings and convert them into something presentable and consumerable by other people. But this is not my ideal way to do it. Ideally, I could take a picture of the white board, and it would be auto generated.
