That one. The posts belong to the people, not the peoples.

HAVE!
Because for anally-retentive self-superior tools like myself it jumps out of the monitor at me and screams in my face. I can't understand how people can write something that is so obviously nonsense. Things lose their meaning without the right grammar.![]()
As long as the general meaning of their post is clear, I don't see any reason to do it.
Could someone remind me, or provide a link as to why an apostrophe after the s [s'] should be used?

The dog's dinner... is how Koreans might announce what's for tea. The apostrophe means there's been a contraction of 'the dog is'.
The dog's dinner... is also (confusingly for non-English speakers) the dinner belonging to one dog, if used in that context.
The dogs' dinner... is the dinner belonging to several dogs.
The dogs' din, ER!... is how you complain to the Queen about her Corgis making a racket while you're trying to play croquet.
All the trailing apostrophe does is save you writing something as ugly as dogs's to indicate the fact that you're talking about something belonging to more than one dog.
For me watching bad or lazy grammar is like watching someone using a hammer to drive a screw... it might work after a fashion, but the finished job will be inferior and potentially unsafe/confusing. If we use the right language tools for the right job we get better understanding, and that's become more important in the internet age, rather than less. Because more people than ever before are using the written word to communicate.
Obviously there's no need to stamp on every typo, but I do think those of us who type English as a first language have a duty to look after it and make life more comprehensible for non-English speakers. Otherwise life online could get very muddy.
Andrew McP... frequently guilty of using a linguistic hacksaw to cut paper.
The confusion arises because "people" already describes lots of human beings without the need for an s. So posts that people have made are people's posts.
In A-Level English I was told that you should add the extra "s" after the apostrophe if that is how you would pronounce the word (e.g. if you would say "dogs" you use "dogs'", but if you say "dogses" you would use "dogs's".) Personally, I add the extra "s" if the word is a singular noun (e.g. "the boss's car") but not if it is plural.
I think "peoples" is valid as well. It's used to describe a specific set of human beings, rather than the general "people", and in that case "peoples'" would be fine. However, most people would use "people"![]()
It's disruptive, anally retentive, annoying, passive-aggressive, and gets in the way of discussion. It also irritates the vast majority of forum readers.
There are better ways to show off than to correct irrelevant spelling and grammar errors. Frankly, it makes the corrector sound like a self-superior tool for the most part. Why should someone else's spelling be of any concern, if the meaning is clear?
Well, thats is just the point. In a vast majority of cases the grammar and spelling is so poor that it is incredibly difficult to decipher what a forum post is trying to communicate. Re-reading posts because someone is too lazy to put in a seconds worth of time just makes the forum unpleasant at best. Typographical errors are one understandable problem we can all put up with, as are the occasional grammatical error. However, spelling is basically done automatically for you with modern browsers and any unknown words are easily located through Google and on-line dictionary resources.
What is really worrying is the repeated abuse of the English language to such an extent that one worries about the future of the country and culture. Much of the youth of Great Britain speaks and writes some of the worst English in Europe now.
Language is incredibly important in modern society and is critical for anyone wanting to peruse a respectable career.
In the end, normal people should welcome friendly correction of repetitive grammatical errors in order to improve their key language skills. As long as the corrections are not abusive or excessive in nature then they do no harm and other people can learn from example.
If that is what you were told in A Level English, I weep for the future of this country.![]()
