Title Confusion

Is there any reason Title Confusion isn't a YMMV item.

Because it reads like an audience reaction - audiences are confused about the meaning of a work's title, or even what the work's title is.

It's a sub-trope of Common Knowledge, which is a YMMV item.

And several of Title Confusion's sub-tropes (I Am Not Shazam, Iconic Character, Forgotten Title, Protagonist Title Fallacy) are YMMV items.

It isn't YMMV because it's been on the wiki since long before we started splitting off YMMV and trivia.

So should it be put on the YMMV homepage?

We would need TRS to do that.

It looks like Title Confusion is also misused to refer to confusion as to what what the title is.
