Bad name, not thriving (37 wicks, 20 inbounds), and it's an old trope. I think the amount of inbounds would be significantly less if it weren't such a common phrase.
Edit: I did a quick wick check, though I didn't write it down, and I'd estimate a 10%-20% misuse, not including some 20%-40% lack of context or ambiguous examples. Almost all misuse is because of the name, as in interpreting the trope as wider than its definition, which is the exact same problem the name has. If someone really wants it formally written down, I can probably do that if asked.
