From what Taka said, the powergrid article was in his TMC mailbox so when he left they went trough it and found the article and ran it without any checks. I suppose they thought he had already fact checked it since he's quite anal about fact checking the articles that he covers as editor. According to him the failure is due to the new TMC concept of running as much material as possible with limited factchecking to get more traffic on the website. Taka and Hendrick were against this new editorial policy of chasing traffic so they got kicked.
Btw Doink I loved your 'It's Called Elite:Dangerous' vid. Laibach's new album is dope and Whistleblowers really went well as soundtrack for the video. Made me pumped about the game, I'm considering shelling out for the beta (which I usually don't do on principle).
