Since you have only received (not so) funny answers: a signature, in
PGP,  serves more or less the same purpose of a handwritten one.

Most of the time it will mean "I am the author of this (email|document|
article)" but not always -- as with handwritten one it could
be used within a contract, etc.

If you have the public key of person A, you can verify with PGP his
signature, so you will be sure the document you received has not been
tampered with.
