I didn’t even know that many suppose “internet” should be capitalized until a few days ago. I was writing something in LibreOffice and the spell checker recommended capitalized spelling. I had seen it a few times, but assumed that those were eccentric outliers.
They are certainly not rules, but there are certainly recent punctuation trends I would like to see adjusted!
It bothers the hell out of me when people punctuate words or phrases as if they were sentences. Floating phrases do not need to start with a capital, or end with a period, as their lack of sentence indicates that they do not communicate any sort of complete idea. Ad companies seem to be the worst offenders, stringing together lists of supposedly evocative phrases. “Trust. Reliability. Your most cherished memories. Because of him.” I guess it’s some post-modern thing where I am supposed to bring my own context so that my brain melds with the phrases, but I don’t have this context. So it comes off merely as pidgin English.
Working differently, but appearing similarly, are people using periods mid-sentence. Presumably to convey some sort of emphasis. It makes a sentence. resemble. a. punctuated. list. Or perhaps they are trying to capture the weird halting delivery style of William Shatner when he gets excited.
Another I encounter frequently is people phrasing something as a question, but punctuating it with a period instead of a question mark. Who would know the difference. Come on, the question mark is only one key away on most keyboard layouts!
