Its not a bad idea, but I think it misses the potential that YC was suggesting.<p>Read the book 'Making Things Talk' - think about the potential of measuring things in the analog world, temperature, weight, flow, force, sound, etc, and correlating these things with enterprise data.<p>Maybe you can start off by measuring things like heartrate, blood glucose levels, physical mobility, dietary intake, etc. For instance, if someone is stressed all day, this probably is going to correlate with productivity.
I think his second assumption that people know who the high performers are is wrong. Often, recognizing competence requires a great deal of competence.<p>Also, I think d0mine's right that kinder people who are easy to work with but not necessarily great performers will get lots of points.
I think this implementation would work at least as well as state of the art modern management techniques do. It's a decent idea.<p>I've daydreamed about something similar. Not sure whether it would be better or worse, but my implementation would limit the amount each person can give, per month. I also struggled with the idea of making it a token economy. Thoughts?
