I used to enjoy listening to This Week in Tech until they started focusing on Twitter, Facebook, and Zynga. I still listen because I genuinely like Leo Laporte's presentation and personality. However, I am disappointed with him and tech journalism in general in how they covered Digg's downfall. They really didn't cover it at all. I really think they turned a blind eye, hoping that things would bounce back because they apparently gained so much traffic from Digg. I understand Digg still gets decent traffic so maybe they just don't want to make things worse.
To me it seemed to be a big story. Kevin Rose was on TWiT a couple episodes ago and they hardly mentioned Digg's problems. Journalism indeed.
