The lads behind Powerline are a bank vice president named Scott Johnson and a lawyer named John Hinderaker. If you read Powerline, you know them better by their fantasy names, Big Trunk (that's Johnson) and Hind Rocket (Hinderaker). I will leave it to the appropriate professionals to determine what they are compensating for, but they have received enormous attention from the despised Mainstream Media and deserve more.
Interesting that Mr. Coleman concludes that the Powerline guys should be getting more attention from mainstream media, presumably in order to uncover just who pulls the bloggers' strings. At least I think that is what he meant. The sloppy use of the pronoun "they" would make it seem it is replacing the antecedant "appropriate professionals". Then again, I'm just an engineer and not a professional writer.
Back to my point about Powerline getting more attention from the main stream media. I think that it would be a good thing for a reporter or columnist to do research into a story on these guys. Most especially if they do the research before they write the column. I tried to find one fact or snippet beyond mere innuendo that indicates that Powerline got marching orders from anyone. What say you Mr. Coleman? Are you ready to do a little reportage of the pick-up-the-phone-and-call-them variety? Explore the site even slightly (oh, no, work!) and you can find the phone numbers of these gentlemen.
*sorry about the registration requirement. I usually make it a point not to link to such sites, but it is almost worth the hassle of coming up with a fake name and a pre-designated junk e-mail address to take a look at this piece of work.
