In the Wall Street Journal today, Jared Sandberg considers the workplace importance of remembering your colleagues' names. I've fallen prey to that challenge myself. Interns come and go, and heck if I can remember the name of every intern we've had here at Fast Company.

But the most embarrassing instance happened just a couple of weeks ago. While working on a project with our interim Admaster Dave Cluett, I turned to Dave and said, "Dave, what's your last name?" (That's my dodgy way of fessing up that I didn't remember his email address.) "Cluett," he responded. Thing was, I knew that. I just blanked. Sorry, Dave.
