This reminds me of the worst part of email: signatures. 5-6 line signatures, where the signature takes up more space than the actual message. They are a pollutant of email threads.
Not to mention those, "This email is confidential..." footers that get auto-inserted at the bottom of every message.
Now that you mention it - in my company for some reason most people dropped this crap and just sign with first name only or no signature at all (of course some people still use multiline sigs with pictures). I don't know the reason, but maybe in one of the ms office upgrades they were lost and nobody bothered to fill them again? :)
