Guys, take into context how the interview is written. There is an editorial addition of mentioning Blackest Night, as inidicated by the closed brackets. THEY made the addition of Blackest Night, not Moore. Moore rarely pays attention to the goings on of mainstream comics because he hates both DC and Marvel for their treatment of him and his work (mostly in the sense that he doesn't own the rights to them, etc).
Now, Blackest Night might be the MOST recent, but Sinestro Corps War is still pretty recent, as well, by only a few years. And yes, there were a LOT of ideas used by Johns that came from Moore's short stories:
-Mogo fighting Ranx (you could also say Mogo, himself, but he's been around for awhile, now) -The planet of Ysmault -The Children of the White Lobe -The Empire of Tears -Sodam Yat
Honestly, I'm surprised the Rot Lop Fan (the Green Lantern that lives in complete darkenss, so doesn't understand lanterns or light or the colour green) hasn't shown his face, yet.
