Email Not Good for Procrastinators
From the article, "Procrastination: Ten Things to Know," newly reviewed in Psychology Today:
"Procrastinators actively look for distractions, particularly ones that don't take a lot of commitment on their part. Checking e-mail is almost perfect for this purpose. They distract themselves as a way of regulating their emotions such as fear of failure."
I'll go out on a limb here and guess that checking blogs has much the same result as well.
