For some reasons the concept of building a network does not sink until it is almost too late.
Professional networking, social media networking and PKM go hand in hand but even when I meet professionals with years of experience, most do not get it.
I receive phone calls several times a year from people who are
1-looking for a more satisfying job
2- desperate because they have been downsized..er.. rightsized
and they want me to help them build a network.

Those same people I have been calling for years to invite them in my communities of practice where we share information, hyperlinks and contacts.
Those same people who attended my learning events where I have been advocating for PKM for years and did not feel the pressure.
Until it is too late...

Thanks Harold for your PKM, your wisdom and your friendship.
