Interesting concept, but little more.<p>Enforcing keystrokes every 5 seconds is a horrible way to facilitate writing.<p>In fact, this reminds me quite a bit of those algorithmic sites that give interviewees a time limit (ie: 30 minutes) to come up with a solution. As the timer approaches 1 minute or so, the timer turns red, blinks, sometimes increases in size, or beeps. I&#x27;m sure if you measured the output during those stressful moments, productivity goes down immensely.
