Having spent a bit of tonight browsing Facebook, something I have mixed feelings about, it struck me after I stumbled across an old school friend who seems to have kept in touch with everyone to wonder hoe it would have worked for Jenkins.
In Dance to the Music of Time there is a certain amount of mystery about what people are doing in between their turns on the metaphorical dance floor with Jenkins. Had he got Facebook then of course he would not only have been able to keep track of Widmerpool and the others but also be able to see what their individual thoughts are and just how many other people they are networking with.
Hate to sound old fashioned but I prefer not to know and to have the wonder of the meetings that Jenkins describes in Dance to the Music of Time.
