Thanks for replying to my questions Harold. Reflecting on your responses and my experience it seems that while I am not in a senior role, there is still ample opportunity for me to contribute to creating effective networks within my sphere of influence. There are small, symbolic changes I can introduce in the teams and communities I am part of. I can use Trojan horses to try different ways of working and observe what happens. I can continue developing my PKM practices and supporting the spread of PKM in my organisation. Most of all I can act as if I am in a network (which I certainly am, even if part of that network is still embedded in a hierarchical framework) - co-operating at every opportunity, and acting as a catalyst and connector.
