My comments about spelling and grammar were only directed towards native speakers. There are many English-as-second-language speakers here, and I have never had a problem understanding their posts. In fact, they always seem to me to be impeccable! I was referring to laziness. Especially a lack of punctuation and basic grammar.
I agree with this. From what I have seen on the internet, ESL speakers (or typers, as it were) often use better grammar, punctuation and spelling than many native English speakers.

The things that get me are typing "U R, prolly, 4" instead of "you are, probably, for", etc. I suppose it's cute the first time you do it, if you are eleven years old, but it gets old really, really fast. I also simply cannot bear to read a post that is 200 lines long, with no paragraphs. Yikes!
