Networks and silos

I liberated this fabulous image from the great information silo of the university's VLE. I thought that was quite appropriate since nothing else seems to be able to get in or out on account of severe weather. Snow to be precise. Last week saw large-scale disruption to the transport network. Most academics were virtually working at home and managed desktops were groaning under the strain. I eased that particular burden by reading Gillian Tett on data silos, and in so doing confronted the irony of living in a highly connected world which is at the same time deeply segmented (I mean what exactly do I know about banking?). So while I'm chewing over some theoretical issues about networking, and online social networking in particular, I started to wonder just how much a space like Facebook has its users locked-in, generating a rather large data silo which can be partially explored from within but not from outside. It's networking, Jim but not as we know it!
