Summary: Go ahead and toss off an unusual term or slang, but don't expect it to actually inform readers if they can't Google it. If you aren't trying to inform readers, exactly what are you trying to do?
I found the unexplained use of the word "Boyerism" in this article to be confusing and unprofessional. I have nothing against the use of slang, or the expectation that readers will need to Google terms: this is the reality of our culture in the age of the Internet and excellent search. However, the casual and unexplained use of a private group's inside joke reveals a lack of awareness of how search interacts with culture. Is it a deliberate attempt to confuse and snub the larger audience, or is in unintentional?
