I was expecting this. Let's try to clear the air on this before it gets messy.
First, Nikki Finke is a very credible journalist. Her resume includes years spent at the L.A. Times.
Due to the clandestine nature of administrations in both the movie & TV businesses, sources, much like politics and sports, have to be protected. People could lose their jobs, especially those, and there are many, who have been forcefully signed to confidentiality clauses.
Publications like Entertainment Weekly & AP dispatches are meant for fan consumption. People like the patrons of a beauty salon waiting their turn in Davenport, Iowa, or in a doctor's office in McKeesport, Pa. Ms. Finke writes about the business side of the biz. The general public does not care about that aspect.
Daily Variety, which recently announced a large number of layoffs, reports on the biz the same way the Wall St. Journal reports on the corporate world, basically(!) just the facts, and very little opinion or commentary.
Deadline Hollywood Daily is a blog, not a publication. As for Ms. Finke's credibility, well, take a few extra minutes on her few posts that you've bothered to read and read the many comments that follow, then see if the posters tend to agree with you or not. She has no lawsuits against her, and the suits themselves have gone to great lengths to try, usually in vain, to keep internal information from her. Journalists like Ms. Finke and a few others are the ones they fear, not the Perez Hiltons of this world.
May I also suggest that you go to the main home page of DHD and scroll through the archives? Many of her headlines start off with the word "TOLDJA!" If you've read Nikki Finke over the years, in print or in cyberspace, you wouldn't question her credibility. Her track record is impeccable.
Clearly(!), you don't like her style, and that's your privilege. No one forces you to read her. Her way with the language reflects the fact that DHD is her blog, not a job under a more conventional work setting, and she's basically(!) being herself.
When R-I tells me to stop posting from Ms. Finke, I will. But not before. Don't read it if you don't like it. You're not Tipper Gore. And you speak for no one else.
It's fine that you obviously don't believe everything you read. That's a good thing. Just keep in mind that it can go more than one way.
One last thing,

get back to me when Knight Rider is off the schedule next spring. I guarantee it'll be gone by the May sweeps, and be virtually hidden by the February sweeps. If I'm wrong, I'll shrug my shoulders and say "My bad!"
