What do you mean "we", Lee? It's pretty much you trying to play you usual self-appointed role as Slog sheriff.
Go re-read my response two comments back as to why I didn't just throw out a number. You think the web people will just look the other way if I go ahead and post one here?
If you're jonesing for hard evidence (and obv I'm not in a position to give it to you), one clue is that the Publicola defectors willingly jumped ship to start a blogging venture that probably doesn't pay too much, assuming it pays at all. Do they do that if the writers make, say, $30K a year? They all do have bills to pay, and if they all resigned, they're probably not collecting unemployment.
