Drinking on the job back in fashion?

Apparently many Silicon Valley firms are providing employees with beer and other alcoholic beverages as a way to compensate for the long hours required for the job. They also use this to bring about a relaxed/creative work atmosphere.  While the idea in and of itself is interesting, the ipad app that they use to track who is drinking the beer also caught my eye.
