I have enjoyed this thread, unexpectedly. I have always been aware that I'm not sure of the use of "Poster and I" and love the rule that you remove "Poster" and see if it still works with just I.
In my job it is quite normal to be given corrections before things are published and I am happy so that I don't send a lot of crap off. I don't feel bad being corrected. This does change how you feel correcting others, it doesn't genuinely feel superior or confrontational, just matter of fact.
OP is quite aggressive in her post and her other thread and I wonder if she is the type of person who really gets angry if anything is pointed out, " can you move your bag off the seat? I was in the queue first? Etc
I think it's within anyone's right to politely point out errors ( I'm looking at you professor) and if you don't like it you are within your rights to disagree. This is a chat forum, for goodness sake.
Probably contraversially, I think it's bullying to say " you can't post X,y,z or I'll report you every time" a) reporting is for abusive and hate filled rubbish or sexual stuff b) MN will not remove a polite poster who points out how to use an apostrophe!
Finally, it's telling that the antigrammar lot have to use such pejorative
language such as 'SPaG police'. How about 'slang jockies' or 'nonsense peddlers? ' You are the ones saying we need to be kind and respectful, how about it the other way round too?
disclaimer: more than happy to be corrected for SPaG!
