I just stumbled across this tool to measure productivity. It's not fancy at all and will most likely work best for NA's or small projects that can be achieved in a few hours. I'll give it a try and will set it as my browser start page for a few days. It keeps a tally of how many goals you achieved within/outside the timeframe you set for yourself, and it'll also show how many goals you skipped in favour of procrastination.

The blurb on the main site also sounds useful. Nothing we haven't heard before, but a good summary of various bits of advice.
