Honestly, I cannot make out what people are saying sometimes, such is their lack of the aforementioned. I'm not being pedantic - but I really struggle to discern what people are saying.
I bet I know who'll be the first to answer this ! ;-)
Yep, knew what you meant, and I think that's one of the important things, minor mistakes in punctuation and spelling don't matter as long as the question/answer is still readable and understandable.
Total lack of punctuation and/or text speak is just not readable to anyone over the age of 12 though!
Punctuation is important to my own typing but does not bother me if others miss it out or make mistakes. It does bother me if the "questions" in Body & Soul go on for too long though!
