Here's one instance of it.

It's cute. It's just amusing because it expects people to act contradictorily to themselves within a single response.

Mm, it depends. To my mind, placing something behind the cut merely puts the decision of whether or not to read it in the hands of the reader, not the writer. Whereas making a post protected lets the writer make the first choice of who reads it.

Others may have different views of it, though, so I see what you're getting at :)

I don't see what you're getting at, since a cut tag can never alter who has the ability to read the text.

I find cut tags are very good for keeping images off friends pages and letting them choose whether to view them and for putting potential spoilers about things I've read or seen into a place where only those who don't mind or have already read/seen it will bother to look.

It's extremely contrary. People are contrary.

Yes, I understand that part. I just wasn't clear on why having a cut tag in a public post is contrary. But now I understand that you meant having a cut tag that you don't intend people to click on.
