I've struggled for years to articulate my ideas and express things clearly, 'specially when it comes to challenging technical problems. One day, I randomly bought a tiny 12" x 5" whiteboard while I was at the dollar store, with the intention of using it to keep a physical todo list.

I eventually reached for it while in the heat of a challenging debugging session with some colleagues, and was surprised with how much it helped me solve the problem at hand. It quickly stopped being a todo-list after this incident. Turned out my inability to articulate things effectively was not because I was stupid, but because I am a predominantly visual thinker.

The fact people are working on tools like this excites the hell out of me!
