quub was a start-up that I worked on with several folks, including George Ruan and Nathan Esquenazi. quub was a commercialization of Nomatic*IM. Basically it was supposed to be automatic status updates that your computer would generate for you based on what it could detect about you from sensors. The ideal case would be to see what someone was doing before you called them on the phone. I still think it was a great idea. It never was able to break-out from the Twitter/Facebook/Four Square enthusiasm that was going on at the time.
