Young or Old. Employed and Secure, or Unemployed and Nailbiting (especially the unemployed) LinkedIn is an absolute MUST social profile. It serves 100 million professionals, business people and is nothing like Facebook or Twitter. It also contains "Business Pages" for companies to be listed, and one of it's best tools is that each group discussion also has Job Listings and Employment Opportunities, which the Discussion Moderators generously list on the Discussion Threads.

In conclusion, LinkedIn is a "must have" social profile for any professional,
and there are many synergies and applications tying your Twitter or Facebook
page to your LinkedIn Profile.
