Look, I probably should start another thread but a serious note...
I make a very good living partly because people struggle with literacy. Things like of/have may not matter on a forum but they sure as hell do on a job application. I would never pick someone up for it on a thread where they are asking for help "should I of done this" for example, but where it's a general comment on a news story, if no one is prepared to point out that a poster is making such a basic mistake, how would you expect them to be aware of it in another written situation?
And yeah I know, uptight teetotal spinster yadda yadda yadda - bring it on.
Sigh.
