instead of crying about it on a forum. contact them yourself and correct them.
email is your sword, correcting them is your battle. don't be afraid, no blood will be spilt...
its just an email after all.
I have proposed putting together a small community of people from this site, and others, who focus entirely on the "Comments" section beneath articles.
To correct the misinformation from the article itself, and the absurd retard-fest that always ensues in the Comments area by the readers.
Don't email the author. Write a comment under the article so both the author, and every reader sees the correction.
Don't be a dick about it. Sound smart, grounded, and rational. Bad attitude will overshadow the information you're conveying.
