In reply to Lilia Efimova.

The best explanation I have is that in dealing with complex problems we have to go at them obliquely. There is no direct line between cause & effect so we have to explore. Social interactions through blogging and twitter increase the chances of serendipitous learning while simultaneously strengthening inter-personal bonds. Because you and I blog, we are able to have this conversation and because we have been conversing for a while I would feel comfortable asking you for help if I needed it. Let me ask my network if they have any other suggestions.
