For the past five to ten years, online social networking sites for career development such as Monster and LinkedIn have been growing and developing.  In the past year, LinkedIn has grown in members by 89% to over 8 million members.  This is a huge increase and suggests the usefulness of online social networking sites for career development.

In particular, it seems that younger workers are especially attracted to these career development sites.  With many of them familiar with the technology, it makes searching for jobs much easier.  Although, workers of all ages use these sites, younger workers find these online social networking sites for career development especially useful because the sites provide “career information that is pre-qualified by its users and, therefore, credible,” which could be difficult information to find if new to job searching.
