Briefly stated, what are the major pros and cons of using social media for MPR purposes?

What will be an ideal response?

Social media and its expanding uses present a novel opportunity for marketers to locate and connect with consumers in ways that are faster and more personal than other conventional avenues of communication. A main concern of MPR professionals active in this new environment is the need, as is the cases in all media, to reach intended audiences through appropriate channels with precise timing. Social media poses an additional concern to marketers: they absolutely must keep up with the rapidly changing social media habits of their target markets. One detraction of social media is its permanency - indelible records of a firm's messages remain digitally inscribed in cyberspace, so evidence of a company's MPR missteps can persist just as long as the positive outcomes of its MPR successes.
