The reason that signing new keys yourself works, is that others can then
follow the trail of signatures.  If someone trusts my key, they can
check my signature on your key, and then your sig on your own key, and
be relatively certain it's you.  At least more certain than downloading
some random key off the net and hoping. :-)

The bigger the web of signatures, the easier it is for someone to find a
verification trail to you.
