I would normally send this privately to the author but there is no way to do so. Since it was published two years ago maybe the misspelling is intentional to subvert the robot censors.
But the word is lewd and not lude. Still a great article and I know no one appointed me chief of the grammar police, Save you personal attacks.
Bad spelling and poor grammar still bothers me. I appreciate it when a reader points out my errors so I can correct them.
As my elementary school teachers reminded me: spelling counts.
