Why are we allowed to post an instant messaging name (for AIM, Yahoo, ICQ, MSN, Skype) but not our e-mail address?

AIM didn't used have email, but now it includes it. Yahoo messenger doubles for email too if it's the same as the original account name, not an alias. I don't know anything about MSN but it's possible some IM contacts would be the same for the email.
