Quoting That Girl.:" Well you can't throw around saying you have an education, then spell like smurf, and completely have smurffy grammar Well you can but you see what happens."
This. I also love the "but this is the internet!" line. Speak/type with conviction and intelligence. If you can't do that, no one will take you seriously.
Smurf, even if someone wrote a grammatical mess because of a lack of education, I'd excuse them. Conviction goes a long way.
But when you write "n" instead of "and," well that is plain smurfing stupidity. No conviction at all.
