People shouldn't use more than one of the same punctuation mark in a row. Now, there's times when it looks like you're doing this where it's OK. For example, the ellipsis looks like three or four periods (you use four when you omit a whole sentence) but it's actually one make w/ multiple parts. The dash looks like two hyphens. That's cool too.

Basically, what I'm saying is using more than one question mark or exclamation point makes you look like a toothless retarded child in print.

I'm really not a huge fan of the exclamation point in general. It's like: Look how important I think I am! I'm shouting like an idiot!

And while we're at it, will you people stop using the question mark when things aren't questions for God's sake. Seriously. You use a period after you write "I don't know" unless you are unsure if you know or not--in which case you should probably stop typing and see a doctor.

I know my grammar is hardly perfect, I use the dash obsessively and I never spell out "w/" or use hyphens in words other than ro-bot but I just had to vent.
