Google Calendars is going down for most of the day on Thursday for some kind of upgrade. Ooh! Upgrade! I wonder if that means new features. It would be nice if the calendars were Blackberry-compatible. I don't use a mobile device myself, but my coworkers have been slow to adopt due to GCal's inability to sync. So, mobile support would be nice, because it would permit users to destroy my carefully-crafted schedules with even more ruthless efficiency than they already do.
