I like reading correct grammar. I don't mind small mistakes in posts on places like PC or other message boards. I mind less in chat when people are typing quickly. However, it bothers me so much when there are typos in things like articles that are published on line. If you are presenting yourself as a professional, your work should look it and be free of typos. It is obvious when the writer and the copy editor are not doing their jobs. I understand live reports needing to get on line quickly, but I don't think that spell check is too much to ask.
