Mark Memmott of NPR reminds blog readers in this story:
Finally, here's a suggestion based on my more than 30 years of reporting and editing experience. Before you submit a comment, ask yourself this question: If I had to put my real name with this, would I hit 'publish?' If the answer is no, the better move might be to hit 'delete.'
This is actually good advice even when you're not trying to be annonymous. While the internet makes it easy to share anything, it also means that you're on stage all the time. Every email, status update, tweet, photo, and video goes out with your name or image on it. And anybody who receives it can spread it to a much wider audience you might never have intended to see it.
Before you hit "Send," "Submit," "Upload," or "Post," ask yourself this question: Would I feel OK if this were shared with (a lot of) other people without my consent? If this answer is no, don't share it.
