leoboiko’s computing log

One thing I noticed in my first international trip is that people who hang in Google Talk, ICQ, MSN, or IRQ have activity patterns based on the time of the day, just like animals. Some are diurnal, or officecular; some are nocturnal, or even caffeiners (extreme nocturnals); some are crepuscular, that is, before-and-after-officecular; dialupers only appear after midnight, and schoolers after lunch, etc. Thus, if you undergo a timezone shift (real or figurative), your IM contact list landscape will surprise you as much as when you hike at night for the first time.
