I think I know of whom Knot refers, but my world is a bit happier I guess, as the thought never passed my mind that the OP was directing this at anyone in particular.

I'm not a huge grammar stickler -especially in formats like a forum, where I actually appreciate (and use) lots of non-standard punctuation to simulate more of a conversational rhythm in a written form. I think if I didn't, I might sometimes come across as a bit deadpan or be misunderstood, because no one else can hear the voice in my head that carries all of the emotion and intonations...

I've also been studying a foreign language recently, and it's an Asian one, so I have little expectation of ever being able to read more than a few words here and there.... The fact that I'm really concentrating on spoken language and trying to understand normal every day conversation has made me very aware of how incredibly different written language and spoken language really are. People simply speaking to one another rarely speak in complete formal sentences - to do so makes you sound very stilted and strange. When we write it's totally different - and I think it is because there isn't immediate context, so writing in sentence fragments becomes very difficult to understand.
