A few mix-ups this week in communications, so let me be clear: If you need to reach me urgently, the most efficient way to do so is with a Twitter @ or DM, especially outside of working hours, and not with a phone call. Yes, I have an iphone, but I keep my phone’s ringer off or on low most of the time. Also, I do not check my phone frequently at work and am not “on twitter” at work so if you call me/tweet me during business hours, please be aware it may be 5pm or later when I can get back at you. And if you call me after business hours, chances are I won’t see the missed call until I go to bed, so please tweet me. Thanks!
