The scourge of the question mark sentence

I doubt you're here for linguistic commentary, but there's something I have to get off my chest. There's a scourge overtaking social media posts, op-eds, even news articles and - horror - books. It's what I call the question mark sentence.

Here are some examples. I've added a translation underneath, just in case you're so afflicted by this new approach to writing that you've forgotten what normal writing looks like.

'I was invited to an interview at 12:30.'

'My colleague was late to the meeting so he apologised and explained he missed the invite.'

Is this starting to ring some bells? LinkedIn is positively brimming with question mark sentences. I'm pretty sure LinkedIn is patient zero. Maybe that's why they irritate me so much. Question mark sentences put me in mind of someone spouting sanctimonious advice on a professional networking platform, or in a TED talk, stating the obvious whilst making out they're God's gift to business. But it's making its way into other arenas...

'One day, a new male carer reveals he has read it all - the sex, the provocation, the dirt. Her response is an indecent proposal.'

'Women are 50 per cent more likely than men to be misdiagnosed when having a heart attack. The main reason is stereotypes.'

I've even seen it in recent books, but I was too annoyed to note the page number so I can't reproduce it. I also saw it on a sign at Blenheim Palace but couldn't bring myself to take a photo. Probably for the best.

I'm not a linguist but if I were to hazard a guess at why question mark sentences are becoming more popular:

• Perhaps some people think they're engaging. Like a little cliffhanger mid-sentence.

• Our attention spans are in ruins thanks to social media, so maybe a question mark break helps our feeble minds hang on until the end of the sentence.

• They sort of suggest the speaker is interesting - it's like a mini interview (with themselves), as if they've said the first part of the sentence then are repeating a question from the audience - 'I had an interview [hey man, what time was it?] the time? 12:30.'

Have you noticed this? Do you like it, or does it annoy you? Once you're aware of it, you'll see it everywhere - sorry.

I'm sure people who are linguists have analysed this, but I couldn't find anything about it. I don't know the technical term for breaking a sentence in the middle with a question mark, so perhaps I was searching using the wrong terms. If you've seen any analysis of this I'd love to hear about it.
