Add one of the first for high-level management: darbs = Geoffrey Darby (my own find). References to TWC, a plane from Atlanta to NY (yeah, he lives in NY) and a You Can't Do That on Television (part of his resume) allusion confirm it.
Rebekah Todd (rebekahtodd) might work at TWC, because she has a lot of TWC people in the following list as well as Geoffrey Darby.
