Facebook has dominated social media over the past decade. According to the Huffington Post, in 2012, Facebook had over one billion active users, and it continues to grow everyday. People use this massive network for a variety of purposes, including social and professional networking.
The argument over whether or not to use such a personal social media outlet rages between the younger and older generations. Most Facebook users over 40 believe the information posted on Facebook is too personal for a professional networking source. Sites such as LinkedIn seem safer and stay true to the idea that professional life and social life should remain separate. Younger generations are beginning to merge these two separate aspects of life. They argue that using Facebook as a professional media outlet allows businesses to get the whole picture of the person they are hiring.
As long as people are able to keep the Facebook pages free from inappropriate or potentially harmful information and pictures, Facebook can be a powerful tool in the job search. However, many people enjoy posting funny, often embarrassing pictures of friends. People who want to use Facebook for professional networking must be careful to keep their pages free of such information. They must recognize that the page is going to be seen by potential employers and treat the page as a sort of resume.
