One thing that frequently makes me uncomfortable is how to handle signing my name at the end of an email.
First off, it indicates who the email was from. Umm, isn't that already pretty clear from the "From" column in your email client. Also, if you are using a signature, you have now stated twice who you are. So it seems kind of like kicking a dead horse to sign your name at the end of the email.
At the same time, however, not signing your name (be it "Dave" or "Al" or "-Jared" or "Yours Truly, Alice") seems rude.
At any rate, until society dictates a formal rule for this, I'll always feel a little socially disoriented when sending emails to anyone other than my family, who I can drop the signature for--after all, they know who I am.
