I'm not sure what your points are other than "people are different, get used to it." Surely there is room for different writing styles and perspectives in the world. That is really not what I was getting at. If that's what you took away from my comment, I would invite you to re-evaluate it.

>Finally, you mention women overusing exclamation points. Maybe they are just being women?

I did mention it, but I did not come up with this on my own. You can read the study I linked to. Calling it "women being women" sounds a bit like the old "boys will be boys" attitude, as if your gender defines your actions or is an excuse.

Instead I'd rather look at why a large group of people feel like they need to express themselves as upbeat and happy. If you read the study I linked to, it talks about this with explanation. I invite you to read some more.
