From proper business friends on Linkedin, there appears to be little B to B introductions with it but some people find it helps in the IT Industry.
Where most consultants like myself win is it is a place to publicise your CV.
I took early retirement from a Major Oil Company in 2010.
Every project I have landed in the past 6 years has come via a Linkedin contact.
In the UK it is mainly a CV store for consultants and agency workers rather than a proper business tool.
Therefore I think it has been great to find work and to keep up with old work colleagues, others who post here, who are not consultants consider it of little use.
