Personally I notice spelling and grammar errors, but that's just because I read a lot, but I also know lots of really smart people who have interesting things to say who struggle with spelling etc. I wouldn't dream of criticising their posts because they spelled a word wrong or missed a comma! And I'd hate to think they hesitated to post or felt the need to proof read what they had written before they posted. one of my best friends in the whole world has dyslexia, and is so sensitive about his spelling, but writes such amazing emails etc, that I just smile and move on and never say a word, how cruel to pick someone up on something they cant help, and maybe miss some of the most interesting words.
