haha, you know the odd thing is, because I'm used to chopping my emails
I now write emails to friends as I'm writing this post here.
I think it's a bit easier to read when you chop e-mails to 75 characters or
so, I've never been one to chop more than that, not typically anyway.
However, I think I will test the longer lines now that you mention it... it really is the way most people write, and would look more authentic you're right.
