Technology: Good, Bad or Ugly?

I am reading Walter Wink's 'The Powers That Be' for a seminar of Friday - and it is giving me an awful lot to think about. Below is a few sentences of reaction from reading the second chapter.

Maybe it is time for us Christians to theologically reflect upon our usage of technology - how can we use it to further the gospel for the glory of God? How is currently being used for the exact opposite?

I hope, at some time, to think more thoroughly upon the issue of technology.
