Collaborative history is a wild ride, as the recent presidential election demonstrated. In October readers were editing and re-editing the entries for President Bush and Senator John Kerry at breakneck speed. And some of it wasn't exactly editing. If you clicked on a picture of Bush in his National Guard uniform to get an enlarged version, you would see a picture of Hitler.
Q : I think the bold part is odd. If "it" refers to "the entries" , "some of themwere not exactly edited" is correct. when "it" stands for "readers",it is correct that "some of themwere not exactly editing."
