I know, I know. Halloween was yesterday. Google bought Jotspot and Wired bought reddit(aftermath). i know i know. those were all history now.

Just saw the following comic from ok-cancel today, not as funny as this one. But I still chuckled.

In case you don’t know what Fitts’ law,”Fitts’ law is a model of human movement, predicting the time required to rapidly move from a starting position to a final target area, as a function of the distance to the target and the size of the target.”

My friend told me that ipod’s scroll wheel actually used fitts law to evaluate and test. I am trying to see if i can find the research article and then post the link later.
