Short version: I had thought the ubuntu 9.04 install was behind this but was mistaken.  It appears that though I did a fresh install, I was doing it on a machine with a separate /home partition.  When I did the install, it saw some configuration that had been done when the machine had eeebuntu on it and that was where using $HOME as the desktop folder originated.  The ubuntu 9.04 install simply recognized it and kept it.<br>
<br>Long version:  This is valid for ubuntu 9.04 and others and includes a bit of informed guesswork.  The specifics may differ some in other versions and distros.<br><br>/etc/X11/Xsession.d/60xdg-user-dirs-update during startup checks if /usr/bin/xdg-user-dirs-update exists and if it does, executes it.  Since it is a binary executable this is a bit of guesswork, but I believe it checks to see if $HOME/.config/user-dirs.dirs exists.  If it does not, it uses /etc/xdg/user-dirs.defaults to create one and to create the directories described using the current locale language. If $HOME/.config/user-dirs.dirs DOES exist it does not do so although I suspect it still checks and adapts to any changes the user has made since the last startup.<br>
<br>I am pretty sure one should be able to return to normal usage by editing $HOME/.config/user-dirs.dirs to add the usual sub-directories (Desktop, Documents, etc) and just do a restart.  It may be that you should recreate the actual sub-directories first but my reading seems to indicate /usr/bin/xdg-user-dirs-update will do it for you during the restart.  I have not verified this.<br clear="all">
