Another way would be to have virtual hosting set up on the blogspot server(s). I doubt that the blogspot people would be interested in doing that, though.
I guess it is good enough now. Besides, anybody that would click on the specific DUFU editions are going to see "BlogSpot" in the address anyways. The main thing is that I can advertise with "DUmmieFUnnies.Com".
I found another BlogSpot Blog that does the same shtick as me. AmericaBlog.Com. Type that name in the URL bog and up pops "AmericaBlog.BlogSpot.Com" Good name.
