Do you realize your question is missing a question mark? lol.
I do think most people learned a minimal amount of grammar and proper usage. However when typing it is hard to get across your inflection without using other methods such as smilies or unusual punctuation. I tend to use "..." often to ad a dramatic pause (or so I like to think). I do think that many people also forget their grammar lessons once they step outside the classroom.
