How much do you coach someone via simple one-on-one conversation? Is that conversation an active listening conversation? Is there an App for that?
Why yes, there is the Talk-o-Meter.
Imagine if we had one of these Apps for pair-programming. It would be a Type-o-Meter. Hooked into the pair programming work station to measure the key strokes of each of the two keyboards. Hey, that sounds like a great idea.
