Web Acknowledge is a firefox plugin that is there for you to log every time you are working on something, and your brain is like, HEY! HEY!!! YOU NEED TO GO CHECK THIS OTHER THING OUT! You click on the little brain icon in your firefox toolbar, type in what you where doing at the time and what your brain wanted you to go check, then you go back to do what you were doing (sorry brain).
This is mostly an experiment to see what triggers those urges to go do something stupid instead of concentrating. I'm also hoping it makes a good tool to help increase your ability to concentrate.
