Since the topic is usage, may I point out that the headline should be "18 obsolete words that never should have gone out of style"?

At least he knew enough to include the comma with “which.”

Nope. "That" is the wrong indicative pronoun; and you cannot "never" anything (wrong word order). Our poster did not use the title given, but even the official grammar-Nazis (editors) of the source site didn't quite get it right:

18 obsolete words, which never should have gone out of style

Since "never" is a contraction of "not ever"," one would not usually say or write, "... which not ever should have gone ..."

Furthermore, it is not customary to begin a sentence with a numeral. Also, the comma here just takes up space and is unnecessary to transmit the thought. So a better way of putting the headline in print would be:

"Eighteen obsolete words which should never have gone out of style"

There. Fixed that.
