There's an article today in the Atlanta Journal-Constitution about how "real" journalism need to be "protected" from "risky" citizen-journalism. In it, the author -- David, Hazinski, the head (for now) of broadcast news at the University of Georgia -- misspells "principles." Twice.

...Citizen reports can be a valuable addition to news and information flow with some protections. ...There are commonly accepted ethical principals -- two source confirmation of controversial information or the balanced reporting of both sides of a story, for example, but adhering to the principals is voluntary...

To this day, I remember how, in third grade, I read a Ramona Quimby book in which she learns that the man who runs the school is the "principal" with a "pal" on the end because he is your pal.
