Frustrated by unanswered e-mail?

A friend sent me a link to this article posted on Linkedin.  It's an article written by Adam Grant, a professor from Wharton. Since most of us have experienced sending an e-mail into a black hole either in our professional or personal life, I found some of his suggestions intriguing.  Like many good articles, the reader needs to realize that some circumstances allow for this approach while others may not.  It's important to recognize your relationship to the intended recipient and anticipate there may be repercussions if the creativity is not well received.  However, in most cases the reality is "what have you got to lose?" What do you think? http://www.linkedin.com/today/post/article/20130624114114-69244073-6-ways-to-get-me-to-email-you-back
