Why does Yahoo Answers get offended by punctuation?

they're just comments don't worry about it. You can still say whatever you want Disregard the text balloons. ;)

If yahoo! told you that you weren't allowed to use full English grammar, it would be a violation of your rights.

Yes, and your grammar is incorrect in English, you should not, for example, be starting a sentence with 'and' this is a fatal Americanism, the appearance of such started the steady decline in standards.

Oddly, I find that message comes up when I correctly use a comma after and in a list, the list for example:

Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

Commonly, the comma before the and on the last item is referred to as a Oxford comma, and is strictly the correct way of form a list in this case.

As for US sites inflicting there poor spelling and grammar on the rest of the world, perhaps here in the UK we should start a Campaign for Real English, silent 'P' anybody?

Anal. I know!

Simply because yahoo is American and uses American "English" ,their grammar and punctuation is less than ours.

The "spell-checker" is bad enough.

Funnily enough typing this I got the same punctuation comment LOL.

That is funny never thought someone would ask this question. I think it gets offend. It reminded me of a teacher coming over and telling me that.

I know right

ayee right enough that always happens hi.
