As you have no doubt heard, the Pulitzers were announced at 3 P.M. ET today (that would be 2pm for those of us who forgot to turn our clocks back and then had to scramble to take a 10am meeting when they had just wandered sleepily into the office at what they thought was the crack of dawn).
No online sites or email newsletters won as such (or were even nominated). However an overwhelming number of winners involved coverage of Sept 11th, and although the Pulitzer release only cites the print editions of such newspapers as WSJ and NYT as winners, we bet these papers' online coverage may have had something to do with it.
