signing keys with expiration

when signing a key with an expiration date, a user is asked:
	Do you want your signature to expire at the same time? (Y/n)

why is the default "yes"?

i use an expiration on my keys as a sort of self-revocation... should the
keys become neglected or abandoned, or if i lose the secret key, the keys
will revoke themselves. if nothing bad happens to me or my secret keys, i
plan to update the expiration on the keys indefinitely.

my concern is that a user who signs my keys might just go with the
default, which could cause me to have a bunch of expired signatures on my
key.

of course it may be desirable, in some circumstances, to expire a
certification signature at the same time as the key expires, but i think
the default should be set to "no".
