One thing I don't think someone is illiterate if English isn't their first language.
In hemanherecomes' I don't think it is a matter of being illiterate or of it not being his first language. I have seen posts where he has made a lengthy post that was perfectly worded. I think he types in the confusing manner that he does by choice.
And I think Wizard might be onto something.
hemanherecomes if you are referring to when you see somewhere in a thread that someone has quoted a statement made by another person and then they put a +1 after the quote that is just a sign of agreement. Has nothing at all to do with karma.
