LinkedIn membership of 45 million is a hot spot of connection opportunities.  Members are executives, politicians, book publishers, investors, Veterans, start-up businesses and more.

The activity I like the best is Open Networking because of the variety if contacts with diverse Internet interests.

Members can search groups, people, companies and more.  I like the public profile feature, that is accessible in more details inside LinkedIn and a general profile of members is searchable in popular seach engines.

Members can view members'

• current and past affiliations and employment
• education
• specialties
• experience ( in years)
• recommendations
• and more
