From the weekly Sam Whitmore's Media Survey teleconference ...Forbes Magazine (famously known for its bloggers attack!! story) managing editor Dennis Kneale:
There are none I religiously read, but I do read Gawker and Romenesko for media coverage. The WSJ daily coverage is more informative for what is going on than any blog.
ValleyWag from that 20-year old kid – why should I turn to that for insight or information?
So, yes, I am on these teleconferences and I figured this would be a fun question to ask different reporters (what blogs do you read?), as it was asked prior at a PRSA event, and the answers were interesting. Sam Whitmore also has a great Podcast for PR people here.
