Twitter is great, but our insatiable appetite for immediacy may be clouding our sense of propriety sometimes. One has only to sit through a corporate meeting in which half the people in the room are replying to texts and e-mails on their cell phones to see just how little face-to-face interaction is respected in some settings. And even when the setting is appropriate, the content (as in Powell’s case) might be better saved for an e-mail to a group of friends, not a post to the world.
Discretion may be the better part of valor, but it’s also a necessary virtue for anyone who wants to practice “safe tweeting.”
