The swinging of a pendulum is a great word picture for describing change. Especially helps for explaining shifts in computing power. The pendulum swung from dumb terminals to personal computers and now to ‘the cloud’.
I mention this in a post at my other blog, Outrun Change: The computing pendulum has swung back to dumb terminals and service bureaus – will it swing back?
There I discuss and link to a post by John Bredehoft.
By the way, my ponderings about the change taking place around us are posted on the other blog. That leaves this blog focused on nonprofit issues.
