That's because it's too expensive to encrypt large text using
assymetric keys.  Effectively, it doesn't matter whether the cleartext
itself or a hash of the same is encrypted using the asymmetric
technology as long as you have sufficient trust in both (symmetric and
asymmetric) methodologies used.<\Raju>

 for a different reason--- It is extremely vulnerable to known plain text
attacks. That it is slow can
be made up to an extent by using fast hardware.

Public Key encryption is a new form of Key-management rather than encrypting
technique and
is best suited for a myrid of protocols like SSH,SET  etc...

Uh, don't do that!  Send your key to one of the global keyservers
instead from where anyone will be able to access it.  Alternatively,
put it up as part of your .plan file if you have a finger'able account
on a public server.  Or publish it in the Times of India if you're
feeling rich ;-)

The method you're suggesting  is correct for everyone else but,
You expect P.Z to check the Times of India or finger your server?  Ho Ho
....Hee Hee
