Personally speaking I wouldn't be likely to be put off from posting because of Bad Spelling or grammar, although I have noticed I am taking much more care about it (not a bad thing)
What would put me off is, in my opinion: wilful misunderstanding by protagantists on both sides of the argument; mis & out of context quotations; and, the use of language I believe inappropriate (and before someone shouts that we are all adults here - I don't remember seeing the "over 18's only" sign on the way in).
I don't believe anyone in this thread or any other has ever been (purposefully) put down by anyone else for there use of grammar or spelling. Mistakes have been pointed out, and it could be argued that when this is done it should be via a private message not in the public forum.
I also believe there is a generational gap, probably exacerbated by the liberal education chiefs, that means that emphasis on getting the "message" across has become more important than getting it right. That surely is the crux of the matter?
Everyone (and I mean everyone) here has argued that the message is the most important thing, Someones ability to craft their message in an appropriate fashion depends on their Knowledge, Education, Time Available, and Interest.
I suggest that some of us have more time than others, and certainly more interest in the written word.
As a tool for communication this is a very poor medium. High Context, High Quality communication relies on Face to Face contact, so that intonation, body language, facial expressions, etc can be taken into account (I read somewhere that this is about 90% of human communication). Low context communication such as swapping messages in a forum are improved when we try to add context (such as smilies) and denigrated when we remove information (such as using text speak).
I like it here, enjoy the debate and am interested in everyones opinions, please please please don't anyone hold back from posting because of anything they have read in this thread.
