Emails

I hate it when you've written a brillant and therefore extremely long email. You think you hit "send" but actually deleted it. So the next draft is much less impressive, and your salutation is always as follows:

Ugh. I just wrote you an amazing email but deleted it so now you'll have to settle for this crappy modified version.

Why do we feel this need to vent to the recipient?

I hate people who put underscores in their email addresses. You're not cool. What happens if it appears as a hyperlink somewhere? I can't tell if it's just a space or an underscore. Plus, I hate the corresponding button on the keyboard. Why is the underscore above the dash? After all, the underscore appears lower scriptwise than a dash. Shouldn't the underscore be on the bottom...thus underscoring the hyphen?

I also hate people with signatures that are longer than the actual email message itself.
