I like question marks
I really like the question mark (and exclamation point) at the beginning of a sentence. That way, when a sentence is really long, I don't have to suddely change my intonation to turn what I thought was a statement into a question (or in the case of an exclamation point, I get to yell and act excited through the entire sentence instead of just the end). It just keeps me aware of what I'm getting myself into. ¡I think I'm going to start doing it in English, too!

¿Are you sure that's a good idea? ¡English speakers might think you are strange!
¡No one can stand in your way!
I've posted English sentences here adding the inverted exclamation, quite by accident. It would take little effort to repeat this error until the rest of the English-speaking world catches on.
