Josh Reynolds, global head of H&K's technology practice, is one of my smartest colleagues, otherwise I would avoid the blatant corporate self-promotion of suggesting you spend 15 minutes watching this interview by Robert Scoble in which Josh talks about why our current economy is making digital the preferred marketing and corporate communication tool. (I have included the link since the embedded video below is only working intermittently.)
And just so you don't think that Josh is acting with such expressiveness only for the camera, I can confirm that he is like this in person . . . especially in client presentations.
