Just another point why it might be a bad idea regardless of intent. It's no skin off my nose if someone corrects my typo's...if they're wrong. However it would drive me bonkers if someone corrected my post incorrectly. Say if I used British spelling or a local phrase that is slightly different somewhere else. My grammar is atrocious, however sometimes I may be using it incorrectly for effect. I wouldn't be a happy bunny if someone then ruined that effect. And then there seems to be major disagreements over some grammar rules. So while I get what people are saying, it just seems like a minefield to avoid.
